Special Issue Information

Dear Colleagues,

This is our pleasure to announce a Special Issue of Nanomaterials on ‘Polymeric Nanocomposites for Energy Relevant Technologies’. As polymer stands is in a pivotal position in the materials science landscape, there are extensive research activities across the globe utilizing polymer as a major component of energy research. Polymers are everywhere in energy relevant technologies ranging from using polymer as template for nanostructured electrodes, separators, binding agent, electrolytes, functional polymer as redox component, even for energy device packaging, EMI shielding applications, semiconducting polymers, water treatment via electrochemical routes, and many more. To cover all these aspects related to exploring polymers in energy-relevant applications, we cordially invite you to contribute to this Special Issue. We believe that our Special Issue will attract huge attention with all of your excellent contributions.

Dr. Soumyadip Choudhury

In this work, a polyaniline/lead sulfide (PANI/PbS) nanocomposite was prepared by combining the in situ oxidation polymerization method and the surface adsorption process. This nanocomposite was applied as a supercapacitor electrode. The crystal structure, nanomorphology, and optical analysis of PANI and PANI/PbS were investigated. The electrochemical performance of the designed PANI/PbS electrode-based supercapacitor was tested by using cyclic voltammetry (CV), chronopotentiometry (CP), and AC impedance techniques in HCl and Na2SO4 electrolytes. The average crystallite size of the PANI/PbS nanocomposite is about 43 nm. PANI/PbS possesses an agglomerated network related to PANI with additional spherical shapes from PbS nanoparticles. After the PANI/PbS nanocomposite formation, there are enhancements in their absorption intensities. At a current density of 0.4 A g−1, the specific capacitance of PANI/PbS in Na2SO4 and HCl was found to be 303 and 625 F g−1, respectively. In HCl (625 F g−1 and 1500 mF cm−2), the gravimetric and areal capacitances of the PANI/PbS electrode are nearly double those of the Na2SO4 electrolyte. Also, the average specific energy and specific power density values for the PANI/PbS electrode in HCl are 4.168 Wh kg−1 and 196.03 W kg−1, respectively. After 5000 cycles, the capacitance loses only 4.5% of its initial value. The results refer to the high stability and good performance of the designed PANI/PbS as a supercapacitor electrode.

In this work, nanostructured TiO2 and poly-3,4-ethylenedioxythiophene (PEDOT) layers were electrochemically prepared over transparent electrodes. Morphological characterization evidenced the presence of nanostructures as planed with 50-nm-wide TiO2 rod formations followed by 30-nm-wide PEDOT wires. Different characterizations were made to the deposits, establishing their composition and optic properties of the deposits. Finally, photovoltaic cells were prepared using this modified electrode, proving that the presence of PEDOT nanowires in the cell achieves almost double the efficiency of its bulk analogue.
