A low-cost paper-based flexible energy storage device using a conducting polymer nanocomposite

Herein, a simple approach is demonstrated for the fabrication of a paper-based flexible symmetrical supercapacitor as an energy saving device with composite functional materials of nickel nanoparticles (Ni NPs) and polypyrrole (PPy).

Modelling of PVDF/CNF Conducting Polymer Nanocomposite

Polymer nanocomposites are highly apricated for the sensor and actuator applications. As they are soft and flexible and can produce higher cyclic loading with good repeatability. But when conductive fillers are woven in the polymer matrix it loses flexibility and enhances the conductivity. Therefore, studying the loading behavior of the nanocomposite becomes important for determining the stability and load bearing capacity of the conducting polymer nanocomposite membranes (CPNC). Therefore, the intent was to design a flexible piezoresistive strain sensor. Finite element analysis (FEA) technique was used for investigating the deformation behavior with a change in stress and strain by applying loads of 0.4 N, 0.6 N, 0.8 N and 1N. Displacement was taken as one parameter for determining the stress intensities in CPNC local regions.
