摘要
通过几种表面活性剂的性能比较发现 :在壳聚糖溶液中加入表面活性剂 Tween2 0 ,可有效改善壳聚糖涂膜保鲜水果时润湿性差的现状 ,界面接触角从原来的 10 5°降低到 5 2°。同时 ,研究了 Tween2
Through compared with the properties of some surfactants, it was found that the wetting ability of chitosan solution on the seedcase was effectively improved and the contact angle decreased from 105° to 52°,with Tween 20 added to chitosan solution. Besides, the relationships between the concentration of Tween 20 and the wetting ability and between the wetting time and the wetting ability were studied.
