23 Jul Conductive silk fibroin material and preparation method thereof
Abstract
The invention relates to a conductive silk fibroin material and a preparation method thereof. The preparation method mainly comprises the following steps: (1) insoluble treatment of silk fibroin material; (2) 2-((2,3-dihydrothieno[3,4-b][1,4]dioxene-2-yl)methoxy)acetic acid activation product graft modification of silk fibroin material subjected to insoluble treatment; and (3) in-situ oxidation polymerization of thieno[3,4-b]-1,4-dioxin-2-methanol on silk fibroin material surface subjected to graft modification. The method can be used for preparing the silk fibroin conductive composite material with the polythieno[3,4-b]-1,4-dioxin-2-methanol grafted on the surface; the surface sheet resistance is 0.9*10<5>-5*10<7>ohm; the preparation technique is simple and mild; and the obtained novel biological material has high application value, and especially can be used as a nervous tissue engineering material and a neural restoration material.
