摘要：
Tribological properties of monomolecular Langmuir-Blodgett (LB) films of octacosanoic acid (OCA) fabricated on silicon substrates by horizontal precipitation (HP) method are studied. The wear resistance of OCA coatings was studied and compared with the stability of both octadecanoic acid (OA) and octadecyltrichlorosilane (OTS) monolayers. It was found that OCA films increase the wear stability of silicon surfaces by 7.5 and 27 times as compared to OA and OTS monolayers, and reduce the coefficient of friction of an initial surface from 0.25 to 0.07. Monomolecular OCA films can be used for the protection of silicon micro-electro-mechanical systems from wear and friction.
