Abstract:

Changes of the surface adhesion forces during the formation of octadecyltrichlorosilane (OTS) self assembled monolayer on glass substrate surface was investigated by Atomic Force Microscope (AFM). The research showed that as the reaction proceeded, the hydrophobicities and the adhesion forces of the sample surfaces increased gradually. After 15 min reaction, the glass surface was completely hydrophobic with an advancing contact angle of 105° and an interfacial energy of 55. 79 mJ•m-2.
