Graft modification on silk with carborane Methacrvlate
摘要
Abstract
Using 1-Carborano-Methoxyethyl Methacrylate as material, graft modification on silk fiber was studied via emulsion radical graft polymerization. The side chains of poly(l-Carborano-Methoxyethyl Methacrylate) were grafted on the silk fibroin macromolecules. The reaction conditions of graft co-polymerization were optimized by orthogonal scheme and the optimum processing conditions was achieved to be: content of monomer in the emulsion was 2.6 %, initiator was 5 %, and the graft polymerization was kept for 100min at the pH value of 3. The structure of the silk fiber before and after modification was characterized by FI-TR and SEM, and thermal decomposition behavior of silk was identified by thermal analysis technology. The TG result showed that the heat-resistance of grafted silk was improved, when the graft degree up to 21.1 %, the mass retention of treated silk was 92.2 % under 300 V, which is higher than the 89.0 % of untreated sample.关键词
