Preparation of hydrophobic self-assembled monolayers on paper surface with silanes

초록

This study was conducted to obtain hydrophobic self-assembled monolayers on paper surface with silanes by a simple and facile method in the vapor or solvent phase. Filter papers with water contact angle over 120 degrees were successfully prepared under sufficient reaction time and silane concentration, and their hydrophobic properties were evaluated by the contact angle measurement and stockigt size test. And the effect of SAM-formation on mechanical properties of paper like wet tensile strength and PPS roughness was also presented. Results from the study reveal the effective reaction time and silane concentration to form stable SAM depending on the coating method and the silane treatments. The fabrication of self-assembled monolayers on the surface of the papers with silanes proved to be a simple process for the preparation of the superhydrophobic papers.
