Graphite/copper nanoparticle-based high-performance micro supercapacitor with porous wet paper-based PVA-PVP blend polymer electrolyte

Structural and optical properties of polymer blend nanocomposites based on PVP/PVA incorporated AgNO3

“…The solutions were thoroughly stirred separately with a magnetic stirrer for 24 h resulting in a uniform liquid. The PVP/PVA blend was prepared in the second step by mixing 0.6 wt% PVP and 0.4 wt% PVA with continually stirring for 1 h. The third step involved dissolving the appropriate amount of AgNO 3 (10,20,30,40, and 50 wt%) in 5 ml of D.W., then heating the PVP/PVA blend to 90 ℃. and stirring continuously.…”

“…The PVA/PVP blends piqued the interest of researchers worldwide because they aimed to optimize these appealing characteristics [17,18]. Researchers examined blends of both polymers in varying quantities [19][20][21][22][23] to monitor changes in physical, optical, and electrical properties and identify which was most advantageous for a particular application. PVA/PVP blends have been created with increasing PVP concentrations to further enhance the permeability and adhesion properties of the polymer blend and lessen its crystalline nature for use as a cell culture biomaterial [24,25].…”

Structure Composition, Morphology and Optical Properties of Chemically Synthesized CuO Nanoparticle

“…There is a nanoparticle based electrochemical capacitors are improved the higher capacitive value which has leads to improve the properties of longer life cyclic, very much power density storage, charge-discharge properties compared normal capacitors and batteries. Although the supercapacitors make ultracapacitor and it involves for energy storage device due to its huge range of application in various fields, such as electric vehicles, electric utilities, load cranes, factory power backup and forklifts [4,5]. Therefore, the growth of energy storage equipment is the significant to the effective use of energy while improving its structure and function.…”
