Table 1. Static CA, CA hysteresis and adhesive force of samples before and after chemical modification with PFTES.
Sample | Static CA | CA hysteresis Δθ = θA-θR | Adhesive force |
---|---|---|---|
SNAs | <10° | * | * |
PFTES/SNAs | 172° | 6° = 175°−169° | 10 μN |
GNSs/SNAs | 164° | 155° = 165°−10° | 254 μN |
PFTES/GNSs/SNAs | 155° | 96° = 161°−65° | 150 μN |
*The values cannot be obtained on the superhydrophilic surface.
