Abstract
In this paper, octadecyltrichlorosilane (OTS) self-assembled multilayer (SAM) films are fabricated on Pyrex glass by dipping method. The hydrophobicity, constituent and surface morphology of OTS SAM at various dipping times in solutions of 1, 2 and 5[Formula: see text]mM concentrations are investigated. Characteristic absorption peaks around 2850 and 2920[Formula: see text]cm[Formula: see text] are observed by FTIR and island-like structures on samples are detected by AFM. After 15[Formula: see text]min dipping time for solution of 5[Formula: see text]mM, water contact angle of the sample reaches the maximum value of 116.4[Formula: see text] with relatively low surface root mean square (Rms) roughness of 0.152[Formula: see text]nm. The critical surface tension ([Formula: see text] of the analyzed sample is 18.2[Formula: see text]dyne/cm. The optimum dipping time in the solution of 5[Formula: see text]mM for a complete SAM film is about 30[Formula: see text]min. The study of the optimal conditions for the formation of integrated OTS SAM has significant scientific and practical values in modification of solid surfaces.
