摘要:

采用自由基乳液聚合法和原位聚合法制备了包含聚苯胺均匀分散在正十八烷中的悬浮体系的交联聚甲基丙烯酸甲酯为囊壁的相变材料纳胶囊(NanoPCMs). 采用扫描电子显微镜(SEM)、差示扫描量热仪(DSC)、热重分析仪(TG)和广角X射线衍射仪(WAXD)等手段分别考察了成核剂聚苯胺的添加量对相变材料纳胶囊表面形态、结晶性能、热稳定性及结晶行为等的影响. 实验结果表明：包含有聚苯胺的相变材料纳胶囊，成核剂的存在对其形貌、粒径、包覆率和结晶行为影响较小，耐热性略有所降低，添加1.5 g 苯胺时生成的成核剂聚苯胺可以有效改善其过冷结晶行为.

Abstract:

Nanocapsules containing polyaniline homodispersed in n-octadecane (n-Oct) were synthesized by free radical emulsion polymerization and in situ polymerization using poly(methyl methacrylate-co- allyl methacrylate) (P(MMA-co-AMA)) as a shell, in which polyaniline was used as the nucleating agent. Furthermore, the surface morphologies, crystallization properties, thermal stabilities, and crystallization process of nanoencapsulated phase change materials (NanoPCMs) were investigated using scanning electron microscopy (SEM), differential scanning calorimetry (DSC), thermogravimetric analysis (TG), and wide-angle X-ray diffraction (WAXD), respectively. The results showed that the addition of aniline as a monomer and polyaniline generated by in situ polymerization had little effect on the morphologies, particle sizes, encapsulation efficiencies, and crystallization process, but the heat resistance properties slightly decreased. Addition of 1.5 g of aniline effectively improved the supercooling crystallization behavior of the nanocapsule.
