摘要 采用红外(FT-IR)、差热分析(DSC)对环氧功能化纳米二氧化硅进行了表征.结果表明,改性纳米二氧化硅上的环氧基团仍保持了其反应性,在聚合物基体聚丙烯或聚苯乙烯中的固化反应其反应机理没有发生变化. FT-IR, DSC were used to characterize the epoxy functionalized nano-silica. The results showed that reactivity of the epoxide groups was remained. The overall curing reaction mechanism of polypropylene or polystyrene were not changed.
