Determination of the specific capacitance of conducting polymer/nanotubes composite electrodes using different cell configurations

Increased response/recovery lifetimes and reinforcement of polyaniline nanofiber films using carbon nanotubes

“…CNTs have previously been combined with both bulk and nano PAni to improve its properties for a range of applications, including actuation and sensing [4,6,[30][31][32][33][34][35][36][37][38][39][40]. For example, Spinks et al report using CNTs to improve the tensile strength and stress loading of PAni for artificial muscles [6].…”

Synthesis and Electrochemical Characterization of Polypyrrole/Multi-walled Carbon Nanotube Composite Electrodes for Supercapacitor Applications

“…The CVs obtained for the other two composite electrodes also followed the same behavior as shown in Figure 2 those observed in the other PPy/CNT composite electrodes. 17,[20][21][22][23] These composite electrodes exhibited no significant change in CV shape even after 500 cycles, which indicates good cycleability of the PPy/CNT electrodes. The symmetric cell assembled with PCNT-20 composite electrode was subjected to charge-discharge cycling in the voltage range of 0 -0.6 V at a constant current of 0.5 mA/cm 2 , and its charge-discharge curves are shown in Figure 3.…”

“…In order to improve the mechanical and electrochemical properties of electrodes based on conducting polymers, the composites of conducting polymers and CNTs have been synthesized for supercapacitor applications. [15][16][17][18][19][20][21][22] It has been shown that CNTs play a role of a perfect backbone for a homogeneous distribution of conducting polymer in the composites. Recently, Kim et al reported that high-specific capacitance and good high-rate capability of polypyrrole(PPy)/CNT composite electrodes could be achieved by controlling pore size in a three-dimensional entangled structure of a CNT film.…”

Polyaniline/porous carbon electrodes by chemical polymerisation: Effect of carbon surface chemistry

“…However, the electrochemical method to prepare polyaniline is limited in terms of mass production [7,8]. In spite of the fact that chemical polymerisation is easier than the electrochemical one [32], composites from carbon and chemically polymerised polyaniline was rarely studied and most of them use carbon nanotubes [6-9, 32, 33].…”

“…Apart from that, swelling and shrinkage of conducting polymers occurring with insertion/deinsertion of counter ions produce mechanical stress which also causes a minor long-term stability [8].…”
