Coating equipment for mass production based on langmuir-blodgett technology

Abstract

A unique technology and equipment for applying to the surface of films with a thickness of one molecule were developed. Technology features allow making the process of film formation continuous, up to the implementation of the Roll-Roll scheme for flexible products. Meanwhile a defect-free coating is formed from 2 to 100 nm in thickness, depending on the structure of the molecules of the applied material. Depending on the nature of the material, coatings can have various consumer properties, in particular, protective ones with high wear resistance in friction processes (they withstand up to 10,000 cycles of abrasive wear with a hard steel fabric under a load of 10 N / cm2), hydro and oleophobic properties, a very low coefficient of friction, resistance to aggressive environmental influences (acids, alkalies, UV radiation). Accordingly, the range of applications of such coatings is quite wide - from display appliance, photonics to nano and molecular electronics. Examples are easy-to-clean coatings for optics, cover glass for solar cell modules, in ophthalmology, in the construction industry (architectural, low-emission and decorative glass), for ceramics, etc. The low coefficient of friction (0.04) makes such coatings promising in friction units.
