Fabrication of electrospun eggshell membrane nanofibers by treatment with catechin

摘要

Optimum processing conditions for the electrospinning of water-soluble eggshell membrane (S- ESM) were investigated. Two biocompatible polymers, poly(ethylene oxide) (PEO) and poly(vinyl alcohol) (PVA), were used to improve the processability of S-ESM for electrospinning in aqueous media. Uniform nanofibers with average diameters of 240 and 335 nm were successfully electrospun for blend ratios at S-ESM/PEO - 95: 5 and S- ESM/PVA = 60: 40 with a solutes concentration of 20 and 18 wt , respectively. Insoluble S-ESM/PEO and S-ESM/PVA fibers were achieved after treatment with catechin and required no toxic or synthetic additives. FTIR spectra indicated that the hydrogen bond formed between S-ESM and catechin was the main interaction that improved the insolubility of S-ESM/PEO and S-ESM/PVA nanofibers in water.
