Abstract:Spin coating was used to produce thin coatings on moderately flat substrates. The coating material solution was dumped onto the substrate and turned off at a high velocity in the range of 1000–8000 rpm, leaving a uniform layer. The ultimate thickness of the deposited film was determined by the angular speed, solution viscosity, and spinning time. The advantages of spin-coating include the ability to achieve very fine, fine, and uniform coverage; however, the problem with large samples is a drawback. In this pa… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
