Corrosion-resistant super-amphiphobic (PVDF-fnAl2O3) coating with thermal and mechanical stability

The thermal and mechanical stability of amphiphobic anti-corrosion coating is evaluated in this study. The coating was fabricated from functionalized nano Al(2)O(3 )and polyvinylidene fluoride (PVDF) and analyzed using FTIR, DSC, TGA, XRD, abrasion and cross-hatched adhesion test analyses. DSC and X...

Description
Summary:The thermal and mechanical stability of amphiphobic anti-corrosion coating is evaluated in this study. The coating was fabricated from functionalized nano Al(2)O(3 )and polyvinylidene fluoride (PVDF) and analyzed using FTIR, DSC, TGA, XRD, abrasion and cross-hatched adhesion test analyses. DSC and XRD revealed the presence of multiple crystalline phases of PVDF in the coating which eventually increased the crystallinity and melting temperature. The removal of the CFx chain from alkylsilane occurred at elevated temperatures, which decreased the repellent characteristic. Overall, the coating demonstrated good thermal stability until the temperature of 450degree celsius with the ISO class 2 adhesion.
