| 摘 要： | 制备了端羟基聚酯胺(HTP)在铝基片上的自组装膜并进行了XPS和STM表征,确认了HTP在铝基片上的吸附组装;由XPS的吸附时间扫描,自组装单分子膜(SAMs)随浸泡时间的延长而增厚,在2 h后达到平衡。由HTP在铝基片的STM三维图可以看到HTP自组装膜以团块形式组成,其间包含孔洞缺陷。提出了铝基片上HTP–SAMs的多羟基结构与膜上孔洞的共同作用是提高环氧类涂层附着力的主要原因。

| Abstract: | Self-assembled monolayers（SAMs） of hyperbranched polyurethane with end-terminated hydroxyl（HTP） on aluminum substrate was prepared and characterized by XPS and STM. Adsorption assemble of HTP on aluminum sub-strate was verified. The thickness of SAMs increased with the increase of aluminum substrate immersing time in HTP solu-tion and the adsorption terminus of HTP on aluminum was reached after 2 h. Molecules conglomeration were seen with holes on SAMs from STM image. It is proposed that common-effect of muti-hydroxyl structures of HTP SAMs and holes on SAMs is the main factor to improve adhesion strength of resins. |
