智能磁性水凝胶的动态黏弹性行为
Journal of Qingdao University of Science and Technology(Natural Science Edition)（2015）
Abstract
先采用溶剂热法制备两种Fe3O4纳米颗粒,再将Fe3O4纳米颗粒分散在甲醛交联壳聚糖水凝胶中以获得Fe3O4智能凝胶,制备出一种新型、绿色的智能水凝胶.采用X射线衍射仪、扫描电镜、流变仪等对产物的形貌结构和性能等进行分析表征.通过采用不同原料配比制备得到了一系列交联的水凝胶,通过施加和不施加磁场,分别获得取向和未取向型磁性水凝胶.重点研究了磁性水凝胶的动态黏弹性行为.磁性粒子的加入提高了体系的储能模量.
