Fabrication of Stable Polyaniline Foams and Their Photoelectric Conversion Behaviors

Abstract

We report a foaming-polymerization method to prepare stable polyaniline (PANI)/polyvinyl alcohol (PVA) foams. The formation mechanism of the foam materials is investigated and the photoelectric conversion properties of PANI/PVA foams are studied in detail. The enhancement of photoelectric conversion behavior in foams is achieved, which has potential application in solar cells and nano-electronics devices.

Flexible and Robust Electro‐Optically Responsive Films Based on Novel Silica/Oligoaniline/Carbon Dots Composite

“…[38,39] Inspired by the photoelectrical features of polyaniline, the photocurrent responsive behavior of SOC film was also investigated under visible light illumination.

“…The photocurrent performance is an important feature for polyaniline, which is generated by the excitation of its conductive main chain leading to charge separation and charge transfer. [38,39] Inspired by the photoelectrical features of polyaniline, the photocurrent responsive behavior of SOC film was also investigated under visible light illumination. Here, the photocurrent responsive behavior of SOC film was recorded using an electrochemical workstation in 1.0 M Na 2 S 2 O 8 solution under 100 mW/cm 2 irradiation.…”

Multi length scale porosity as a playground for organic thermoelectric applications

Single Solvent‐Based Film Casting Method for the Production of Porous Polymer Films

“…For example, the breath figure method involves generating condensed water droplets on the surface of evaporating polymer solution, which requires tight control over the humidity environment of the film drying site . A foaming‐polymerization process has also been investigated to prepare a polyaniline (PANI)/polyvinyl alcohol (PVA) porous foams, where a specific amount of aniline and PVA were dissolved in water followed by incorporation of air bubbles utilizing a mechanical stirrer. Ammonium persulfate was then added with continuous stirring for a further 8 h to form the polymerized aniline foam.…”
