| Popis: | Conductive superhydrophobic cotton fabric was fabricated by assembling carboxylated and aminated multiwalled carbon nanotubes and modifying with polydimethylsiloxane. The cotton fabric possessed superhydrophobicity with a CA of 162°, and was successfully applied in oil-water separation with high separation efficiency and great reusability. Additionally, the conductive fabric-based pressure sensor exhibited stable and regular responses in human motion detection including finger bending, wrist movement, walking and running. Owing to the excellent water repellency of the fabric, the pressure sensor could work even under wet and humid conditions, which may pave a novel way to further broaden application field in high-performance electric sensors. |
