Soluble and electrically conductive polyaniline‐modified polymers: Incorporation of biocompatible polymeric chains through ATRP technique

Abstract

This article describes the incorporation of biocompatible polymeric chains [poly(2-hydroxyethyl methacrylate) and poly(N-isopropylacrylamide)] into the polyaniline backbone through atom transfer radical polymerization technique to produce soluble and electrically conductive polyaniline-based materials. The chemical structures of all samples as representatives were characterized by means of Fourier transform-infrared and proton nuclear magnetic resonance spectroscopies. The electroactivity behaviors and electrical conductivities of the synthesized samples were verified under cyclic voltammetric conditions, and the standard four-probe method, respectively. In addition, the thermal behaviors and morphologies of the synthesized samples were investigated by means of thermogravimetric analysis and scanning electron microscopy, respectively. We envision that the synthesized polyaniline-modified polymers may be find applications in biomedical fields such as tissue engineering, mainly due to their water solubilities, electrical conductivities, and biocompatibilities.

Thermally driven characteristic and highly photocatalytic activity based on N-isopropyl acrylamide/high-substituted hydroxypropyl cellulose/g-C3N4 hydrogel by electron beam pre-radiation method

“…26,27 In addition, the peak at 1661 cm −1 is indexed to the carbonyl stretching vibration peak of NIPAAm (C=O, amide I band). 28 It is obvious that the –OH stretching vibration peak and aliphatic –CH 3 deformation peak on the ring have disappeared after the introduction of NIPAAm. The successful synthesis of NIPAAm/HHPC hydrogel can be confirmed by the formation of new chemical bonds and the retention of original groups.…”

Research progress on preparation methods of water-soluble polyaniline

“…Massoumi 100 incorporated biocompatible poly(N-isopropylacrylamide) (PNIPAAm) and other polymers into the PANI backbone through ATRP to prepare soluble PANI materials. The chloroacetyl chloride first reacted with eigenstate PANI to prepare PANI-Cl, and then PNIPAAm was polymerized onto the PANI chain by ATRP technology.…”

Preparation of bagworm silk/polyaniline composite

“…Recently, soluble and electrically conductive polyaniline-based copolymers were synthesized through atom transfer radical polymerization as a highprecision technique. 19 Polyaniline/fiber composite and polymer blend with polyaniline exhibit electromagnetic interference (EMI) shielding. Communication devices, such as mobile phones, can emit electromagnetic waves; however, they cause malfunction of electronic equipment.…”
