New technology is constantly required for updating new generation flexible devices, such as stretchable sensors, flexible electronics, and actuators. In the present study, a stretchable strain sensor, and actuator were developed based on room‐temperature‐vulcanized (RTV) silicone rubber reinforced with carbon nanotubes (CNTs), nanographite (GR), and CNT‐GR hybrids. A CNT‐based strain sensor developed for RTV silicone rubber showed improved stiffness and brittleness. For example, at 5 phr of filler loading, the compressive and tensile modulus for the CNT‐reinforced RTV silicone matrix improved by 287% and 240%, respectively. Similarly, the improvements in the compressive and tensile modulus were moderate for the CNT‐GR hybrid (210% and 235%) and low for GR (135% and 125%). The improved brittleness resulted in a higher fracture strain of 170% and 155% for the CNT‐GR hybrid and GR, respectively. The improved mechanical properties were tested in real‐life applications of actuation. The actuation displacement at a filler loading of 2 phr increased to 1.65 mm (CNT), 1.25 mm (CNT‐GR), and 0.08 mm (GR). From 2 to 8 kV, the actuation displacement increased by 825% (CNT), 830% (CNT‐GR), and 32% (GR). The strain sensor showed a stretchability of >100% (CNT) and >100% (CNT‐GR). In addition, the gauge factor was higher for the CNT‐GR hybrid composites. The durability measurements showed that the change in resistance was negligible for up to 5000 cycles in both the CNT and CNT‐GR rubber composites. A series of experiments confirmed that compared to the composite based on RTV silicone rubber and CNT, the CNT‐GR hybrid showed a robust flexibility and stretchability as a piezo‐resistive strain sensor and actuator.

“…Preparation of Macroscopic CNTs Thin Films: The macroscopic CNTs thin film was prepared according to the previous reports. [26,50] CNTs (20 mg) were dispersed in the anhydrous ethanol (20 mL) by 1 h consistent sonication to form stable, uniform dispersions. The CNTs dispersion was injected into the water surface by a syringe.…”

A multiple stimuli‐responsive actuator with an ability of rapid and sensitive responding is highly desirable for the development of biomimetic actuation applications. Herein, a bilayer actuator with fast and sensitive responses to acetone vapor and light stimuli is reported based on polyvinylidene fluoride (PVDF) membrane with a hierarchical porosity and macroscopic carbon nanotubes (CNTs) assembled film. The CNTs film with uniform and tunable thickness is prepared by a macroscopic interfacial assembly strategy and transferred integrally onto the PVDF membrane. Under the infrared light, this CNTs/PVDF bilayer actuator can bend rapidly within 1 s and generate large stress. Moreover, for the acetone vapor stimuli, the actuator bends within 0.19 s and also reverses in 1.24 s to the initial state, showing sensitive and fast responses to acetone stimuli, as well as outstanding stability and repeatability.
