Abstract
A process for preparing a metallic nanoparticle-coated substrate is described, by transferring a metallic nanoparticle coating from a microporous film.
Claims15
A method of providing a nanoparticle coating on a substrate comprising;
- a) providing a substrate and providing a microporous membrane having a discontinuous coating of vapor-deposited metallic nanoparticles on the surface of the microporous membrane;
- wherein the metallic nanoparticles comprise individual particles or agglomerates of particles having an average major dimension of less than 100 nm,
- b) contacting the substrate and the nanoparticle-coated microporous membrane with sufficient pressure to transfer at least a portion of said nanoparticles from said nanoparticle-coated membrane to a surface of said substrate.
