Studies on the superhydrophobic properties of polypropylene/polydimethylsiloxane/graphite fluoride composites

Abstract The polypropylene/polydimethylsiloxane/graphite fluoride (PP/PDMS/GF) composites are prepared with dynamic curing technology by simple blending of polypropylene, graphite fluoride and polydimethylsiloxane, and then their superhydrophobic properties are investigated. The results indicates that the static WCA reaches 148° with a sliding angle 6° for surface sandpapered PP/PDMS/GF = 100/20/15 composite, which supplies a much economical and convenient method for preparing superhydrophobic materials.
