摘　　要：研究了漆酶催化桥接过渡单体丁子香酚的黄麻织物接枝丙烯酰胺的改性方法,考察了改性黄麻的亲水性。元素分析证明漆酶/t-BHP体系能催化引发黄麻-g-丁子香酚上的CC双键与丙烯酰胺发生聚合反应,利用微量凯氏定氮法测定了黄麻-g-丁子香酚接枝丙烯酰胺的接枝率,并对反应条件进行了优化。热失重(TG)分析表明改性黄麻织物耐热性提高;静态接触角、水滴润湿时间表明改性黄麻织物亲水性显著提高。Hydrophilicity of eugenol-bridged jute fabric graft polymerization with acrylamide via Laccase was studied.Elemental analysis showed that Laccase/t-BHP system can cause the C C of jute-g-eugenol graft polymerization with acrylamide.The grafting rate of jute fiber-g-eugenol grafted acrylamide wwa measured by Micro-Kjeldahl method.The best reaction conditions were figured out.TG was carried out to prove the heat resistance of modified jute fabric improved.The contact angle and dripping time showed that modified jute fabric hydrophilicity was improved significantly.
