Characterization of poly(2-Hydroxyethyl Methacrylate) Scaffolds for Tissue Engineering
Physical properties of scaffolds intended for myocardial tissue regeneration were studied. Mechanical properties and degradation rates were evaluated for degradable scaffolds composed of poly (2-hydroxyethyl methacrylate) (pHEMA) crosslinked with polycaprolactone (PCL). pHEMA copolymerized with tetraethylene glycol as a crosslinker served as a control. Fibroblast cells were used for cytotoxicit...
متن کاملPoly (2-Hydroxyethyl Methacrylate) Macroporous Cryogel for Extracorporeal Medical Devices
Poly (2-hydroxyethyl methacrylate) PHEMA monolithic cryogels were synthesized by free radical polymerization at -12°C for 18 hours and produced spongy, elastic and macroporous gel matrix. Scanning Electron Microscopy (SEM) measured structural properties of PHEMA monolithic cryogel matrix to visualize pore morphology. Mechanical properties of PHEMA monolithic cryogel such as storage modulus, com...
متن کاملSwelling behavior of poly (2-hydroxyethyl methacrylate) copolymer gels
Hydrogels based on 2-hydroxyethyl methacrylate/dimethyl-aminoethyl methacrylate copolymers were prepared by gamma radiation-inducedco-polymerization at low temperature (−78◦C). The swelling behavior of hydrogels was studied by immersion of the polymer discs in buffered solutions at pH from 2 to 10. The hydration process was followed gravimetrically by measuring the water uptake of the discs as ...
متن کاملBiocompatible Bacterial Cellulose-Poly(2-hydroxyethyl methacrylate) Nanocomposite Films
A series of bacterial cellulose-poly(2-hydroxyethyl methacrylate) nanocomposite films was prepared by in situ radical polymerization of 2-hydroxyethyl methacrylate (HEMA), using variable amounts of poly(ethylene glycol) diacrylate (PEGDA) as cross-linker. Thin films were obtained, and their physical, chemical, thermal, and mechanical properties were evaluated. The films showed improved transluc...
متن کاملThe effect of polar copolymers in protein absorption on contact lenses on 2-Hydroxyethyl methacrylate(HEMA)
For the purpose of increasing the permeability to oxygen and equilibrium water content in contact lenses, polar copolymers with nonionic monomers such as 2-hydroxyethle methacrylate(HEMA) Is used. By adding the polar monomers to (HEMA), the permeability to oxygen and equilibrium with water content is increased and also the absorption of proteins on lens surface is changed. In this research, the...
