Wear stability of superhydrophobic nano Ni-PTFE electrodeposits

Abstract Commercialization of superhydrophobic surfaces remains rather limited due to the high costs of many fabrication processes and the poor understanding of the long term stability of their non-wetting properties. In this study, degradation of a recently developed superhydrophobic nanocrystalline Ni-PTFE composite made by electrodeposition was evaluated by a linear abrasion test on SiC abrasive media. For comparison, the same abrasion test was also conducted on a commercially available superhydrophobic spray-on treatment to benchmark the wear performance of the Ni-PTFE composite. Due to the microstructure of the Ni-PTFE composite coating, remarkable non-wetting properties were observed after extensive abrasive wear.
