Flame Aerosol Synthesis and Thermophoretic Deposition of Superhydrophilic Tio2 Nanoparticle Coatings

A highly controllable and tunable technique for the production of thin coating layers of TiO2 nanoparticles by aerosol flame synthesis and direct thermophoretic deposition is presented. Different flame reactor operations were used to study the effect of particle size and film morphology on coating p...
