论述了偶联剂、表面活性剂和复合改性剂对硫酸钙晶须表面改性方法及改性机理的研究现状。硫酸钙晶须改性主要是利用改性剂与晶须表面存在的羟基、硫酸钙等发生反应,改变晶须在基体中的分散性、相容性和粘合强度等,从而使晶须达到较好的改性和应用效果。
The research status of calcium sulfate whisker modification method used coupling agent,surfactant and composite modifier and modification mechanism were discussed.The modification of calcium sulfate whisker mainly useds these modifiers to react with the hydroxyl and calcium sulfate on the surface of the whisker,and changed the dispersivity,compatibility and adhesion strength of the whiskers in the matrix,thus making the whisker better modified and applied.
