Preparation and adhesion of a dual-component self-assembled dual-layer film on silicon by a dip-coating nanoparticles method

A novel microfabrication method is presented to fabricate with spatial control a dual-component self-assembled dual-layer film on silicon by dip-coating nanoparticles. In this research, the same chain length carboxylic acids with a fluorocarbon backbone chain and hydrocarbon backbone chain were composite-prepared on 3-aminopropyltriethoxysilane (APS) self-assembled monolayer (SAM). Film wettability was determined by measurement of contact angle, and thickness was determined with the ellipsometric method. Changes in adhesive properties of the film are determined by atomic force microscopy (AFM).
