Special Issue Information

Dear Colleagues,

Conducting polymers have emerged as a fascinating class of materials at the intersection of chemistry, materials science, and electrochemistry. These organic compounds possess a unique blend of properties, combining the flexibility and processability of polymers with the electrical conductivity of metals, while still retaining the structural characteristics of polymers.

Furthermore, over the past few decades, conducting polymers have garnered significant attention from researchers and technologists due to their diverse range of applications in the field of electrochemistry.

This Special Issue aims to gather the latest advances of applications and illustrate the versatility and significance of conducting polymers in the field of electrochemistry. Some of the notable applications for conducting polymers in electrochemistry include sensors, energy storage, electrochromic devices, and actuators, among others.

In this paper, we report a titanium dioxide/polypyrrole/phosphorene (TiO2/PPy/phosphorene) nanocomposite as an active material for supercapacitor electrodes. Black phosphorus (BP) was fabricated by ball milling to induce a phase transition from red phosphorus, and urea-functionalized phosphorene (urea-FP) was obtained by urea-assisted [...] Read more.
In this paper, we report a titanium dioxide/polypyrrole/phosphorene (TiO2/PPy/phosphorene) nanocomposite as an active material for supercapacitor electrodes. Black phosphorus (BP) was fabricated by ball milling to induce a phase transition from red phosphorus, and urea-functionalized phosphorene (urea-FP) was obtained by urea-assisted ball milling of BP, followed by sonication. TiO2/PPy/phosphorene nanocomposites can be prepared via chemical oxidative polymerization, which has the advantage of mass production for a one-pot synthesis. The specific capacitance of the ternary nanocomposite was 502.6 F g−1, which was higher than those of the phosphorene/PPy (286.25 F g−1) and TiO2/PPy (150 F g−1) nanocomposites. The PPy fully wrapped around the urea-FP substrate provides an electron transport pathway, resulting in the enhanced electrical conductivity of phosphorene. Furthermore, the assistance of anatase TiO2 nanoparticles enhanced the structural stability and also improved the specific capacitance of the phosphorene. To the best of our knowledge, this is the first report on the potential of phosphorene hybridized with conducting polymers and metal oxides for practical supercapacitor applications. Full article
