Self-healable Chitosan Bioaerogel by Dual Crosslinking |
| 초록 |
Aerogel is a porous material used in various fields including biomedical engineering. Bioaerogel requires biocompatibility and structural stability against physical and chemical stimuli. Herein, the self-healable chitosan aerogel was prepared by dual crosslinking. Chitosan was dissolved in 1-butyl-3-methylimidazolium chloride (BMIMCl). The complex viscosity of the chitosan/BMIMCl solution in higher concentration (＞ 3 wt%) showed gel-like behavior over entire frequency range. The hydroxyl groups were covalently crosslinked by epichlorohydrin (ECH) while the amino groups were electrostatically crosslinked by itaconic acid (IA). The chemical and electrostatic crosslinkings of the aerogels were analyzed using FT-IR spectra. The concentrations of ECH and IA influenced the water absorption capacity of the aerogel. The fractured aerogel was self-healed after few hours with contact to each other with help of water. The prepared aerogel shows potential as a wound healing matrix. |
