4. Conclusions
- (1)
- The surface of the electrodes became denser and formed a conductive path as the EC concentration increased. All the inks exhibited a typical non-Newtonian shear thinning behavior, enabling smooth extrusion and printing.
- (2)
- The PPy particles were uniformly distributed on the nanofiber surface, providing an excellent conductive path. The film started to decompose above 200 °C, which could meet the requirement of thermal stability for most applications.
- (3)
- The above electrodes and CF@PPy film were assembled into a pressure sensor, which could indicate the change in pressure and had a high sensitivity (0.0584 KPa−1).
- (4)
- TENG was constructed by using CF@PPy film as a tribo-positive friction layer, which could achieve a high electrical energy output (voltage = 29.78 V, current = 2.12 μA).
