Open-air spray plasma deposited UV-absorbing nanocomposite coatings

摘要: We demonstrate the deposition of mechanically robust UV-absorbing nanocomposite coatings with a newly developed dual-source method involving ultrasonic spraying and open-air plasma deposition. Nanoparticles coating matrix are independently deposited which eliminates difficulties associated preparing composites high mass fraction well-dispersed nanoparticles in matrix. Nanocomposite containing different concentrations silica, ceria, both titania ceria were successfully good nanoparticle dispersity, transparency over visible range, effective absorption UV wavelength, enhanced mechanical properties. Moreover, films on several substrates including polycarbonate to low processing temperature this method. Coatings film thicknesses systematically studied terms their surface morphology, optical properties Accelerated photostability testing nanocomposites demonstrates significantly performance compared existing either polymeric or organic UV-absorbers.
