| titleOfInvention | Self-repairing super-hydrophobic anti-drag elastomer film and preparation method thereof |
| abstract | The invention relates to a self-repairing super-hydrophobic anti-drag elastomer film and a preparation method thereof, wherein a sharkskin V-shaped groove structure is copied on the surface of an elastomer, and a polyacrylamide-polyfluoroalkyl acrylate block copolymer capable of forming a micro-nano structure by self-assembly is grafted, so that the self-repairing super-hydrophobic elastomer film has the self-repairing super-hydrophobic performance, the static water contact angle reaches more than 150 degrees, and the rolling angle is less than 10 degrees. The drag reduction film is attached to a rotor of a rotational viscometer for drag reduction performance test, and the drag reduction rate can reach 20%. The invention has the advantages that: 1. the super-hydrophobic resistance-reducing method and the bionic resistance-reducing method are combined together, so that the resistance-reducing film has a good resistance-reducing effect in a laminar flow state and a turbulent flow state; 2. after the surface chemical components of the polyfluoroalkyl acrylate grafted on the surface of the super-hydrophobic membrane are damaged, the membrane can be self-repaired by soaking in a solvent or heating at high temperature, so that the membrane has a super-hydrophobic effect again. |
