Highly strong and sensitive bilayer hydrogel actuators enhanced by cross-oriented nanocellulose networks

Wei Liu et al.

Summary: A temperature-responsive bilayer hydrogel actuator with an anisotropic structure in mutually perpendicular directions was developed. The actuator demonstrated superior actuation ability and mechanical performance due to the cross-oriented structure of the two hydrogel layers. It showed high lifting capacity, bending speed, tensile strength, and elongation at break, and further cross-linking improved its mechanical properties. This bilayer hydrogel has potential applications as artificial soft tissue materials and intelligent actuators.

Creating ionic pathways in solid-state polymer electrolyte by using PVA-coated carbon nanofibers

Feng Huang et al.

Summary: The ionic conductivity of solid epoxy-ionic liquid nanocomposite electrolytes can be significantly enhanced by incorporating carbon nanofibers coated with Poly(vinyl alcohol) into the polymer phase. This modified solid electrolyte shows a 38-fold increase in ionic conductivity, making it a promising candidate for high-performance structural batteries or supercapacitors. Additional alignment of carbon nanofibers during curing of the epoxy did not further improve the electrical and mechanical properties of the solid electrolyte.
