Abstract:
1. A method for forming a nanoparticle film, comprising the steps of: preparing a nanoparticle solution, which comprises a solvent and supersaturated nanoparticles with surface ligand molecules; dip coating a substrate to the nanoparticle solutions to form a first monolayer of the nanoparticles on the substrate, the first monolayer of the nanoparticles constructing the nanoparticle film and each nanoparticle of the first monolayer comprising a hidden side toward the direction of the substrate and the exposed side toward the direction opposite to the substrate; converting the exposed surface ligand molecules of the exposed side of the nanoparticles into functional groups phobic to the solvent by plasma modification; and dip coating the substrate into another nanoparticle solution comprising the solvent and supersaturated nanoparticles to form one or more monolayers of nanoparticles on the first monolayer.
