Negative Capacitance Based on Isomeric Polythiophene in Action In this study, we demonstrated that arranging positive and negative capacitance materials in series, based on isomeric polythiophene, led to a notable increase in total capacitance. Furthermore, the application of negative capacitance (NC) technology in supercapacitors (SCs) construction offers the potential for energy storage capabilities surpassing fundamental limits.

Isomeric Polythiophene: Promising Material for Low Voltage Electronic Devices In this investigation, we present empirical observations detailing the manifestation of substantial negative capacitance (NC), reaching up to -1F, within iodine-doped isomeric polythiophene (IPTh-I2). NC observed in our case is not transient but stable enough to be measured for as long as the optimum concentration of iodine dopant is available.

Nanocrystalline TiO2 and conjugated polyimide are good composite materials for solar energy harvesting applications. Vat dyes have a specific high color fastness property with high wavelength absorption. By applying this property of vat dyes, we synthesized Safranin O and a perylene 3,4,9,10-tetracarboxylic dianhydride (PTCDA) based conjugated polyimide through the condensation polymerization technique.
