Acrylates (ethyl acrylate, ethyl methacrylate, and methyl methacrylate) are ingredients found in artificial nail products. By copolymerising PHEMA with functional groups, the swelling and mechanical properties can be tuned to allow for the encapsulation of cells, such as fibroblasts (Uludag and Sefton, 1993). Methacrylates are used in a range of industries and applications, including: Electronics and Computers. Poly(2-hydroxyethyl methacrylate) (pHEMA) is a nonbiodegradable hydrogel used to fabricate soft contact lenses, and therefore has advantages in spinal cord repair applications as a clinically-approved polymer. Hydroxyethylmethacrylate or HEMA is the organic compound with the formula H2C=C(CH3)CO2CH2CH2OH. Pragnesh N. Dave, Ankur Gor, in Handbook of Nanomaterials for Industrial Applications, 2018. Hydroxyethyl methacrylate is a clear, colourless liquid with a sweet odour which is soluble in water. 4.23) can be radically manipulated through copolymerization and by cross linking [159]. Besides controlled drug release and protein release, the hydrogel also has potential application in development of synthetic skin, breast augmentation, contact lens, etc. Figure 13.33. The process has many advantages such as a short one-step reaction occurring at atmospheric pressure, ambient air, and room temperature in water. It was invented by Drahoslav Lim and Otto Wichterlefor biological use. xH 3 PO 4. Research group from Portugal has developed novel stereolithographic fabrication technique for the fabrication of multimaterial graded scaffolds using UV and thermal energy for cross-linking the polymer (Pj, 2008). Poly(hydroxyethyl) methacrylate (PHEMA) is a stable, optically transparent hydrophilic polymer that is one of the most widely applied hydrogel biomaterials. Physically cross-linked PVA networks with optimal elastic properties, high water-content, and macroporous structure were obtained (Mastrangelo et al., 2017) through cryogelation (see Fig. Modification of surface charge, with the addition of quaternary amine groups or of a second methacrylate subtype [321], is another approach taken to improve cell/neurite migration and encapsulation, as many cell types adhere better to a positively charged surface. Further improvements in supraspinal neuronal regeneration were achieved by filling the conduit channels with extracellular matrices and soluble trophic factors (FGF-1 and NT-3). PHEMA-based hydrogels can be engineered to possess similar water content and mechanical properties as tissue, and exhibit excellent cytocompatibility. When formulated as a hydrogel block, insertion of pHPMA into a thoracic hemisection improved animal locomotor scores and electrophysiologic parameters over controls in addition to supporting axonal regeneration within the hydrogel matrix [332] (Table 58.4). The first method has used GMA in combination with MMA to produce materials which have water contents in the range of 30–42%. Hydroxyethyl Methacrylate. What is 2-Hydroxyethyl methacrylate and where is it found? 2-Hydroxyethyl Methacrylate is a hydroxyester compound and a resin monomer used in desensitizing dentin. Photopolymerized hydrogels of this polymer are used in 3D scaffold formation for soft tissue engineering (Bártolo et al., 2009). Microfluidic techniques were employed to create functional concentration gradients by casting the scaffold using two or more inlet ports for differential mixing coupled with rapid polymerization. CAS Number: 52628-03-2. Articles of 2-Hydroxyethyl methacrylate … Cell surface interactions in longitudinally oriented macroporous scaffolds were further modified using pHEMA copolymers with cholesterol methacrylate and ethylene dimethacrylate [342], or with ECM peptides [323], to successfully bridge a hemisection cavity with regenerated neural tissue. Figure 58.21. pHEMA tubes as copolymers with MMA. Many studies aim to modify the properties of PHEMA to improve the degree of hydration, degradation, mechanical properties and transport properties. J.J. Roberts, P.J. An acrylamide gel-microemulsion composite system was used to remove aged synthetic adhesives (e.g., Mowilith DM5, a commercial adhesive based on vinyl acetate and n-butyl acrylate) from canvases (Pizzorusso et al., 2012; Chevalier et al., 2008). Nanoparticles with controlled size and composition are then obtained. Nicolas N. Madigan, Anthony J. Windebank, in Principles of Tissue Engineering (Fifth Edition), 2020.

Poly hydroxyethyl methacrylate (PHEMA)-based hydrogels are the first synthetic hydrogels for pharmaceutical applications. Deposition of polymer hydrogel on metallic implants improves the compatibility of implants and also develops controlled release device such as stent or microchips (De Giglio et al., 2011). Data submitted and used for the evaluation are: Non‐toxicological data and information Wego is an importer of 2-Hydroxyethyl Methacrylate to numerous countries around the world. George Wypych, in Self-Healing Materials, 2017, A polymer network (poly(2-hydroxyethyl methacrylate)) and single-walled carbon nanotubes connect through host-guest interactions.64 The resulting material shows bulk electrical conductivity, proximity sensitivity, humidity sensitivity and it is able to rapidly self-heal without external stimulus under ambient conditions.64, The thin conducting wires can easily break during use, and the whole device fails to function as a result.65 The self-healable conducting wires were obtained by the wrapping of electrically conducting nanomaterials, such as carbon nanotubes and Ag nanowires, around polymer fibers (Figure 11.8).65 These wires were developed for wearable and portable electronics.65, Multi-walled healing fibers are fabricated through a direct, one-step tri-axial electrospinning process to encapsulate healing agents inside the fibers with two distinct protective walls.66 Self-healing systems based on ring-opening metathesis polymerization and an amine-epoxy reaction use these tri-axial fibers.66 Solutions were loaded into the syringes connected to concentric nozzles, and the flow rate of each layer was controlled by separate pump (Figure 13.33).66. hydroxyethyl methacrylate’) consists of a mixture of phosphoric acid, mono-, di- and triesters with 2-hydroxyethyl methacrylate (HEMA) and diphosphoric acid, mono-, di-, tri- or tetraesters with HEMA. Figure 9.7. Glyceryl methacrylate (GMA) is more hydrophilic than HEMA because of the fact that the monomer contains two hydroxyl groups (Fig. We use cookies to help provide and enhance our service and tailor content and ads. The scanning electron microscopy images show the porous structure of the gels. An estimated BCF of 1.3 was calculated for 2-hydroxyethyl methacrylate(SRC), using a log Kow of 0.47(1). It is a clear, colorless liquid with a characteristic odor. Besides high load bearing ability, this polymer also exhibits the resistance to crack propagation 18. Macroporous pHEMA scaffolds [322] were evaluated in a dorsal hemisection injury bridged with four pHEMA composites, demonstrating an improvement in axonal regeneration into the core of the scaffold and a reduction in astrocyte infiltration in the positively charged scaffold. Among several derivatives, methacryloyl-β-alanine (MBA) has a particularly low solution viscosity and a high compressive strength. Chemical hydrogels, such as acrylamide or p(HEMA)/PVP gels, which are characterized by a macroporous structure, can be also used as containers for nanostructured cleaning fluids such as microemulsions and micellar solutions. It was shown that when the combined gel + microemulsion system is placed onto hydrophobic grime, the latter is solubilized in the microemulsion droplets, which in turn diffuse back into the gel. Polyhydroxyethylmethacrylate is hydrophobic; however, when the polymer is subjected to water it will swell due to the molecule's hydrophilic pendant group. It is a colorless viscous liquid that readily polymerizes. There are various applications of PHEMA-based hydrogel in biomedical field. Methyl methacrylate, or MMA, is a substance used in the manufacture of a variety of plastics and other products. Structure, properties, spectra, suppliers and links for: (Hydroxyethyl)methacrylate, 868-77-9. In the second step, the monomer was intercalated in the clay interlayer spaces and then the polymerization process was promoted. Besides, they are highly hydrophilic. (A): image of FT 1; (B): image of FT 2 (bar is 1 μm). PHEMA in dry state is hard and brittle and after swelling it becomes flexible. The softened adhesive is then easily removed without inducing mechanical stress on the canvas fibers. Early applications as pHEMA sponges placed into dorsal hemisections [315] soon evolved into multilayered guidance channels [316] which immobilized NGF [341] and BDNF [317] for sustained release and which had longitudinally oriented channels of tunable size created by templating the pHEMA over PCL microfibers [318]. Early work demonstrated the capacity of a colloid pHPMA gel, with [330] or without [331] the incorporation of ECM peptide, to support regeneration when injected into a complete transection defect. MMA is used widely and can be found as an additive in concrete, in adhesives, artificial joints, dentures, hairspray, nail polish, paints, textiles and windows. In this work, using UV free-radical polymerization technique, a pH-sensitive membrane with interpenetrating polymer network has been formed for delivery of targeted drug.
