以丙烯酸树脂为基体,通过纳米微粒直接分散法,制备了四针状纳米ZnO/丙烯酸树脂复合材料.当硅烷偶联剂的用量为纳米ZnO的10%(质量分数)时,可获得ZnO微粒分散性好的复合材料,对该材料进行的红外吸收测定表明,复合体系的透射率随着纳米ZnO的加入急剧下降,具有良好的红外屏蔽性能,同时该涂料也表现出良好的抗菌及抗静电性能.
Tetrapod-like nano-ZnO whiskers were prepared by physical method. For small size and surface effect of nano materials, aggregation tendency should be resolved before the practical application. Hence, different dispersing methods were designed and examined. Nano-ZnO/acrylic resin composite coatings were prepared to form nano functional coatings. It was observed that the composite with uniform distribution of nano-ZnO in the acrylic resin resulted in having multi-functionalities. Different treatment methods for tetrapod-like nano-ZnO whiskers demonstrate an intensified affect on the final functional effects of composite coatings. The coatings can be used for plastic materials etc. Furthermore, the mechanisms of the functions were also analyzed for the sake of understanding.
