以熔融法制备了聚苯并噁嗪(BZ)/凹凸棒土(AT)复合材料。利用DSC考察了凹凸棒土的引入对苯并噁嗪单体开环温度的影响。通过透射电镜(TEM)观察了凹凸棒土在基体树脂中的分散情况,并对于复合材料的动态机械性能和耐热性进行了研究。
The polybenzoxazine/attagulgite composites were prepared by melt method. The effect of the attagulgite on the curing temperature of the benzoxazine monomer was investigated by DSC. The dispersion of attagulgite in the matrix was observed hy TEM, and the dynamic mechanical property and thermal stability of the composites were also studied.
