Abstract

This article discusses the influence of substrate wettability and air humidity on the process of nanoparticle patterns formation in evaporating microdroplets. The process of self-assembly of polystyrene and aluminum oxide particles on the glass covered with titanium, tungsten, carbon, and teflon was investigated.<br> The droplet evaporation time and the obtained packing of particles with increasing hydrophobicity of substrates were evaluated. The influence of air humidity on the evaporation dynamics and on the process of nanoparticles self-assembly is revealed.
