Electrospinning of the hydrophilic poly(2-hydroxyethyl methacrylate)and its copolymers with 2-ethoxyethyl methacrylate

摘要

The goal was to electrospin 2-hydroxyethyl methacrylate-based biocompatible polymers and prepare submicron fibres(nanofibers)for biomedicinal applications.Syntheses of poly(2-hydroxyethyl methacrylate)(HEMA)and its copolymer with 2-ethoxyethyl methacrylate(EOEMA),and their characterization by viscometry and molecular weight are described.Their relation to electrospinning is discussed.Electrospinning of HEMA homopolymer from water-ethanol is successful for molecular weights 6.31×10~5 and 1.80×10~6 g/mol.Electrospinning of HEMA/EOEMA copolymers is feasible from ethanol.
