摘要: Superhydrophobic surfaces with both excellent mechanical durability and easy reparability based on polytetrafluoroethylene/room temperature vulcanized silicone rubber (PTFE/RTVSR) composites were prepared by a simple abrading method. The surface energy of RTVSR matrix decreased the increasing volume fraction PTFE particles, rough microstructures created abrading. A water droplet exhibited contact angle about 165° ± 3.4° sliding 7.3° ± 1.9°. Such superhydrophobic showed strong against sandpaper because in way abrasion, fresh exposed still superhydrophobic. In addition, micro-structures elastic composite will be compressed deformation to avoid being broken during friction cycles when cotton fabric was used as an abrasion surface. rebound renew original structures load is withdrawn. Therefore, PTFE/RTVSR are advantage construct better resistance. More importantly, such superhydrophobicity can repaired regeneration process within few minutes damaged or polluted organic contaminant.
