摘要： 采用交流阻抗谱和接触角的方法研究了γ-APT硅烷的单分子自组装膜在热镀锌钢板表面的成膜过程,以及γ-APT硅烷自组装膜和γ-GPT硅烷的相容性.实验成功制备硅烷单分子自组装膜.组装开始时硅烷分子水解生成硅醇键的一端快速吸附在锌的表面并形成了Si—O—Zn键,硅烷分子之间的硅醇键随即脱水形成Si—O—Si键,从而自组装成为有序、规律排布的单分子自组装膜,组装10 h后膜的完整性最好,随后形成连续性较差的混杂膜.经过10 h组装后的γ-APT硅烷自组装膜与γ-GPT硅烷具有良好的相容性.

Abstract: The synthesis of γ-APT silane self-assembled monolayers (SAMs) on hot-dip galvanized steel (HDG) and the SAMs compatibility with γ-GPT silane were investigated by electrochemical impedance spectroscopy (EIS) and contact angles analysis. The results showed that the SAMs of the γ-APT silane are deposited on HDG surfaces. First, the SiOH groups of γ-APT are absorbed quickly onto the HDG surfaces to form Si-O-Zn. Then Si-O-Si covalent bonds are formed between the γ-APT silane molecules and the zinc surface, releasing water as a byproduct. The SAMs become stable and the compatibility between the SAMs and γ-GPT silane is good when HDG sheet is immersed in the silane for 10 hours. After that the SAMs is no continuity as a mishmash.
