Stable Superhydrophobic and Antimicrobial ZnO/Polytetrafluoroethylene Films via Radio Frequency (RF) Magnetron Sputtering

In this study, superhydrophobic ZnO/Polytetrafluoroethylene (ZnO/PTFE) films with water droplet contact angles (CA) observed as high 165° and sliding of (SA) <1° have been prepared on glass substrates by RF magnetron sputtering. The PTFE was wrapped a nano-rod made ZnO film properties while providing excellent UV resistance compared to hexadecyltrimethoxysilane (HDTMS) hydrophobic agents. upper surface the rough coated PTFE, most underlying coating bare ZnO, which could well make bacteria. For Gram-negative strain, E. coli, cell viability count ZnO/PTFE sample (3.5 log reduction, 99.96%) conspicuously lower than that ZnO/HDTMS (1.2 93.87%) under 1 h illumination light, showed has better photocatalytic property ZnO/ HDTMS films. also good mechanical robustness, is an important consideration in their widespread real-world adoption.
