Preparação e caracterização de filme transparente polimérico hidrofóbico para aplicação em superfícies de vidro

Abstract

Consumer demand, encourages the development of new products by organizations, including elevated levels of quality, price and time compatible with the market. Seeking to develop a functional water-repellent, easy production and application, we elaborated a polymer composition capable of generating a transparent film using poly (vinyl chloride), paraffin wax and nitrobenzene. The developed product behavior is compared to commercial products of greater acceptance and sales in the domestic market, according to a report of June 2010, the magazine Quatro Rodas, as follows: Water off and Waterlux. The product with the highest contact angle between the liquid and the substrate was developed: 102º, followed by Water off: 84º and then the Waterlux: 65º. To start rolling drop, the glass product developed needs to be tilted 7º, the Water off: 6º and the Waterlux: 10º. Through the characterization by atomic force microscopic (FEG-SEM) observed the formation of irregularities in the microstructures, and the material developed had a greater number of them, thus justifying the reduction in wetting drops and efficiency in sliding of the same. It was found that the film produced remained uniform thickness throughout extension applied glass, and its effective adhesion to the substrate contributed to the durability of the film on the substrate. The composition of the developed material nonpolar materials containing only prevents the solubilization of the film by water droplets polar ensuring efficiency and durability application.
