The High-density Polyethylene/Ethylene Propylene Diene Monomer/Graphite Fluoride (HDPE/EPDM/GF) composites are prepared by dynamic vulcanization technology. The composites with sea-island structure which contributes to excellent mechanical properties can be easily recycled and re-thermoplasticized. A unique processing technology is designed to make graphite fluoride distributed on the phase interface of the material. The prepared phase interface with aggregated GF has very low interfacial energy, and this unique phase interface greatly improves the hydrophobicity of the material. The static WCA reaches 153° with a WSA 12° for composite containing 15 phr graphite fluoride. What’s more, the composite material has relatively good wear resistance, and when the surface of the composite material is damaged, the composite material can still maintain excellent hydrophobicity. Therefore, the superhydrophobic material prepared by this convenient method can be used for potential industrial application.
