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

• The polypropylene/polydimethylsiloxane/graphite fluoride (PP/PDMS/GF) composites are prepared.
• The study of superhydrophobicity showed that the WCA reaches 148° with a sliding angle 6°.
• Sandpapering and addition of GF can apparently increase superhydrophobicity.

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.
