The demand for flexible conductive materials has motivated many recent studies on conductive polymer–based materials. However, the thermal conductivity of conductive polymers is relatively low, which may lead to serious heat dissipation problems for device applications. This review provides a summary of the fundamental principles for thermal transport in conductive polymers and their composites, and recent advancements in regulating their thermal conductivity. The thermal transport mechanisms in conductive polymer–based materials and up‐to‐date experimental approaches for measuring thermal conductivity are first summarized. Effective approaches for the regulation of thermal conductivity are then discussed. Finally, thermal‐related applications and future perspectives are given for conductive polymers and their composites.

“…Conducting polymers, born in 1977 with the work of MacDiarmid [11], have received vast attention in various fields such as biomedical applications [12], bioelectronics [13], energy storage [14] and anti-corrosion [15]. This interest is due to their tunable electrical conductivity that can be achieved through, facile polymerization, doping and their soft organic material properties [16].…”

In this paper, we report an electrochemical material for nicotine detection in aqueous solution by using glassy carbon electrode (GCE) electrodeposited with Nickel(II) phthalocyanine‐tetrasulfonic acid tetrasodium salt (polyNiTSPc) in Tetra n‐bütil ammonium hydroxide (TnBAH) alkaline solution. The detection performance of the polyNiTSPc/GCE and the reaction mechanism of nicotine electro‐oxidation process is investigated using Cyclic Voltammetry (CV) and Square Wave Voltammetry (SWV) techniques in 0.1 M phosphate buffer solution (pH 7.5). The conductivity properties of the bare GCE and polyNiTSPc/GCE were analysed using Electrochemical impedance spectroscopy (EIS). The surface morphology of bare GCE and polyNiTSPc/GCE are characterized by Atomic Force Microscopy (AFM). PolyNiTSPc shows high catalytic activity for the electro‐oxidation of nicotine, with the limit of detection at 146 nM nicotine. PolyNiTSPc/GCE can be used as a biosensor with very low detection limit for nicotine. Electrode process for nicotine oxidation is diffusion controlled, including irreversible one‐electron transfer attributed to the nicotine/nicotine‐Δ1′,(5′)‐iminium ion conversion on the polyNiTSPc coated electrode. Electrochemical measurements indicated that the polyNiTSPc against nicotine plays a similar role as CYP2A6 enzyme which catalyses the intermediate reaction product of nicotine‐cotinine transformation in most mammalian species.

“…PANI was then grown on Pt–Ni nanooctahedra/C through direct polymerization of aniline for preparation of Pt‐Ni@PANI hybrids. The coupling of PANI and the Pt–Ni nanooctahedra/C is attributed to interaction between N atoms/π–π bonding in PANI and the surface of Pt–Ni nanoctahedra/C (Figure b–f and Figures S1 c–g, and S2 b–f in the Supporting Information). PANI shells with different thicknesses were realized by varying the amount of aniline injected into the reaction mixture.…”

Controlling the morphology and composition of nanocatalysts constructed from metals and conductive polymers has attracted attention owing to their great potential for the development of high‐efficiency catalysts for various catalytic applications. Herein, a facile synthetic approach for ultrathin‐polyaniline‐coated Pt–Ni nanooctahedra (Pt‐Ni@PANI hybrids) with controllable PANI shell thicknesses is presented. Pt–Ni nanooctahedra/C catalysts enclosed by PANI shells with thicknesses from 0.6 to 2.4 nm were obtained by fine control over the amount of aniline. The various Pt‐Ni@PANI hybrids exhibited electrocatalytic activity toward the methanol oxidation reaction that is highly dependent on the thickness of the PANI shell. Pt‐Ni@PANI hybrids with the thinnest PANI shells (0.6 nm) showed markedly improved electrocatalytic performance for the methanol oxidation reaction compared with Pt‐Ni@PANI hybrids with thicker PANI shells, Pt–Ni nanooctahedra/C, and commercial Pt/C due to synergistic benefits of ultrathin PANI shells and Pt–Ni alloy.
