本發明提供一種油性奈米金屬粒子複合物及其製造方法。該油性奈米金屬粒子複合物主要包括奈米金屬粒子及一油性聚合性高分子,例如聚胺酯。油性聚合性高分子係螯合並作為奈米金屬粒子之載體,使奈米金屬粒子達到奈米級之分散。本發明之製造方法主要係使油性聚合性高分子與一金屬離子於一溶劑中進行螯合反應,再加入一有機分子還原劑,將銀離子還原成銀,並形成大小為5-100nm之油性奈米金屬粒子/聚合性高分子複合物。
The present invention provides an oil-dispersible composite of metallic nanoparticles and a method for synthesizing the same. The composite primarily includes metallic nanoparticles and an oily polymeric polymer such as polyurethane (PU). The oily polymeric polymer serves as a carrier of the metallic nanoparticles by chelating therewith so that the metallic nanoparticles are dispersed uniformly. In the method of the present invention, the metallic ions are first chelated by the oily polymeric polymer and then reduced into nanoparticles. The composite of the present invention is about 5 to 100 nm in particle size.
