Abstract

ABSTRACT 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.

二十烷酸单分子Langmuir–Blodgett薄膜的形成及其摩擦学性能

研究了用水平沉淀法(HP)在硅衬底上制备的八碳酸(OCA)单分子Langmuir-Blodgett (LB)薄膜的摩擦学性能。研究了OCA涂层的耐磨性，并与十八烷酸(OA)单层膜和十八烷基三氯硅烷(OTS)单层膜的稳定性进行了比较。结果表明，OCA薄膜使硅表面的磨损稳定性比OA单层和OTS单层提高了7.5倍和27倍，并使初始表面的摩擦系数从0.25降低到0.07。单分子OCA薄膜可用于保护硅微机电系统免受磨损和摩擦。

期刊介绍： Providing a common forum for all soft matter scientists, Soft Materials covers theory, simulation, and experimental research in this rapidly expanding and interdisciplinary field. As soft materials are often at the heart of modern technologies, soft matter science has implications and applications in many areas ranging from biology to engineering. Unlike many journals which focus primarily on individual classes of materials or particular applications, Soft Materials draw on all physical, chemical, materials science, and biological aspects of soft matter. Featured topics include polymers, biomacromolecules, colloids, membranes, Langmuir-Blodgett films, liquid crystals, granular matter, soft interfaces, complex fluids, surfactants, gels, nanomaterials, self-organization, supramolecular science, molecular recognition, soft glasses, amphiphiles, foams, and active matter. Truly international in scope, Soft Materials contains original research, invited reviews, in-depth technical tutorials, and book reviews.
