One step phase separation process to fabricate superhydrophobic PVC films and its corrosion prevention for AZ91D magnesium alloy

Highlights
- Independent superhydrophobic polyvinyl chloride (PVC) film was prepared by phase separation process.
- The superhydrophobic PVC film showed excellent stability in acid, alkali and salt corrosive solutions.
- This film was prepared on magnesium surface protecting it from corrosion.
- This method was simple and universal.
