技術摘要 / Our Technology: |
本發明係關於一種高分子型聚胺,由聚醚胺及連接劑聚合而成。連接劑可為酐、酸、環氧化物、異氰酸或苯乙烯/馬來酐共聚物(SMA)。本發明亦關於一種以高分子型聚胺穩定奈米銀粒子之方法,高分子型聚胺作為穩定劑或分散劑,與銀鹽水溶液混合後,再以還原劑還原銀粒子,可形成一含有奈米銀粒子的有機或水溶液。該含有奈米銀粒子的溶液可再進一步經加熱或減壓過程以蒸除去水或溶劑,以提高其固含量。並可再度稀釋成穩定性高且不聚集之奈米銀粒子分散液。
The present invention discloses a polymeric polyamine which can be produced by polymerizing polyoxyalkylene-amine and a linker. The linker can be anhydride, carboxylic acid, epoxy, isocyanate or poly(styrene-co-maleic anhydride) copolymers (SMA). The present invention also discloses a method for stabilizing the Ag nanoparticles with polymeric polyamine. The polymeric polyamine serving as a stabilizer or dispersant is mixed with a water solution of silver salt and then a reducer is provided to reduce the silver ions and form an organic or a water solution of Ag nanoparticles. Water or solvent of this solution can be further removed through a heating, freezing or decompression process, and thus solid content of the solution can be increased. The concentrated solution also can be diluted to obtain a stable dispersion without aggregation.
