  The “fog phenomenon” describes the formation of tiny droplets of water on different surfaces. In day-to-day life, fog affects the light transmission and damages the visibility of different surfaces, such as plastic packaging, lenses, mirrors and windshields. In this study, a new thin coating onto polypropylene films, made of proteionoids and proteinoid nanoparticles for fog prevention, is presented. The proteinoids and proteinoid nanoparticles were synthesized by thermal step-growth polymerization of amino acids and therefore are non-toxic, biodegradable and biocompatible. The anti-fogging ability of proteinoids and proteinoid nanoparticles was discussed in terms of wettability, surface chemistry and morphology, that were measured by contact angle and atomic force microscopy. The efficiency of the anti-fog coatings was also tested by hot and cold fog tests to examine the o.. View More»
