Preparation of super-hydrophobic films based on waterborne polyurethane and their hydrophobicity characteristics

•Super-hydrophobic WFPUs films were prepared via one-step spray method under a mild experiment condition.•These films exhibited their extreme water resistance and rapid drying performance.•The superhydrophobic angle of WFPU4 film was 153.82°. Super-hydrophobic films are applied in various antifoulin...
