Actuation of two types of electro-active paper actuators composed of functionalized carbon nanofiber, polypyrrole, and regenerated cellulose (FCNF/PPy/RC) and functionalized carbon nanofiber, ionic liquid, and regenerated cellulose (FCNF/IL/RC) is evaluated for different preparation processes. FCNF/PPy/RC nanocomposite films are prepared by dispersing functionalized carbon nanofiber and polypyrrole into cellulose solution in DMAC/LiCl, and then casting the solution onto glass. FCNF/IL/RC nanocomposite films are fabricated simply by adopting a bimorph configuration with a regenerated cellulose-supported internal ionic liquid electrolyte layer sandwiched by electrode layers with a view to getting quick and long-lived operation in air at low applied voltage. The electrode layers include functionalized carbon nanofiber, ionic liquid and regenerated cellulose. The results indicate that the bending displacement decreases with increasing frequency and increases with increasing voltage for both types of actuators. These low voltage driven solid state actuators show maximum stress and strain of 12.73 MPa and 3.0%, respectively, which are comparable with other low-voltage driven solid-state electro-active polymer actuators. The advantages of these types of actuators are their ability to perform well in air and easy process of fabrication.

The paper presents results of studies of the optical and electromagnetic properties of the WO3/rGO electrochromic nanocomposite films obtained by mechanical spraying of a water-based dispersed solution with WO3/GO particles and heat treatment (annealing) at a temperature of 300°C in an inert argon atmosphere for 24 hours. As a result, an electrically conductive phase of reduced graphene oxide rGO and crystalline WO3 were formed.

Electrically Conductive

The electrically conductive, transparent, and flexible self-standing thin nanocomposite films based on copolyamide matrix (coPA:Vestamelt X1010) modified with 2D Ti3C2Tx (MXene) nanosheets were prepared by casting and their electrical, mechanical and optical properties and then, were investigated. The percolation threshold of the MXene filler within the coPA matrix was found to be 0.05 vol. %, and the highest determined electrical conductivity was 1.4 × 10−2 S·cm−1 for the composite filled with 5 wt. % (1.8 vol. %) of MXene. The electrical conductivity of the as-prepared MXene was 9.1 S·cm–1, and the electrical conductivity of the MAX phase (the precursor for MXene preparation) was 172 S·cm–1. The transparency of the prepared composite films exceeded 75%, even for samples containing 5 wt. % of MXene, as confirmed by UV spectroscopy. The dynamic mechanical analysis confirmed the improved mechanical properties, such as the storage modulus, which improved with the increasing MXene content. Moreover, all the composite films were very flexible and did not break under repeated twisting. The combination of the relatively high electrical conductivity of the composites filled with low filler content, an appropriate transparency, and good mechanical properties make these materials promising for applications in flexible electronics.
