以非离子表面活性剂P123为模板剂,ZrOCl2·8H2O和Ce(NO3)3· 6H2O为原料,制备出CeO2-ZrO2介孔粒子.采用油酸对介孔CeO2-ZrO粒子进行有机改性后,与笨乙烯原位聚合得到CeO2-ZrO2-聚苯乙烯杂化材料.该杂化材料的热分解温度达到417℃,与纯的聚苯乙烯分解温度相比有显著提高;当CeO2-ZrO用量达到m(CeO2-ZrO2)/m(苯乙烯)=2/100时,杂化材料的拉伸强度达到最大值42.3MPa;当CeO2-ZrO2用量达到m(CeO2-ZrO2)/m(苯乙烯)=3/100时,杂化材料的缺口冲击强度达到最大值3.18 kJ/m2;有机分子进入CeO2-ZrO2介孔材料孔道内的方式和表面包覆作用,促进了无机粒子与基体间形成强有力的界面粘合,极大改善了聚苯乙烯的力学性能和热性能.
