Controlling on Attraction Forces of Water Droplets on Surfaces of Polypropylene Nanocomposites
Ahmed Thabet Mohamed,Khaled Ebnalwaled Abdelfattah Ahmed 한국전기전자재료학회 2018 Transactions on Electrical and Electronic Material Vol.19 No.5
In this work, Sol gel method was used to prepare polypropylene nanocomposites; some diff erent types of the nanoparticles(clay, ZnO, SiO 2 and TiO 2 ) and diff erent concentration (1, 5 and 10 wt%) were used to control on the attraction forces of waterdroplets on surfaces of polypropylene nanocomposites. The prepared polypropylene nanocomposites were characterized byFTIR, SEM, dielectric constant, contact angle, wetting energy, spreading coeffi cient and work of adhesion measurements. Experimental results deduced that clay and ZnO nanoparticles reduce the dielectric constant of polypropylene, while SiO 2and TiO 2 increase this value. It has been reported that the wettability of the prepared nanocomposites is reduced by increasingcertain nanoparticles ratio, which indicate the ability of the obtained nanocomposites for packaging and battery casesapplications.
