Electrochemical activation of carbon nanotube/polysulfone composite electrodes for enhanced heterogeneous electron transfer is studied. The physicochemical insight into the electrochemical activation of carbon nanotube/polymer composites was provided by transmission electron microscopy, Raman spectroscopy, electrochemical impedance spectroscopy, and cyclic voltammetry. Dopamine, ascorbic acid, ...

This review summarizes the current state of polymer composites used as dielectric materials for energy storage. The particular focus is on materials: polymers serving as the matrix, inorganic fillers used to increase the effective dielectric constant, and various recent investigations of functionalization of metal oxide fillers to improve compatibility with polymers. We review the recent litera...

Composite polymer electrolyte (CPE) membranes, comprising poly (vinylidene fluoride) (PVdF)/poly (methyl methacrylate) (PMMA), BaTiO3 as ceramic filler and LiBF4 as the lithium salt were prepared using a solution casting technique. The prepared membranes were subjected to XRD, FT-IR, impedance spectroscopy and thermal stability studies. The incorporation of nanofiller greatly enhanced the ionic...

The paper presents and discusses a method to achieve beneficial electrochemical effects mediated by interfaces in an ionic conducting polymer matrix. The beneficial effects include enhanced ionic transport, catalysis of anodic oxidation reaction, and stabilization of the lithium-electrolyte interface in lithium-based electrochemical cells. Polyethylene oxide (PEO) doped with LiN(SO2CF2CF3)2 (Li...

Polymer composites are among the most rapidly growing research fields in material science. Polymer composites are adding a great deal of material that is more durable and useful as compared to the conventional material. Properties of composite materials greatly depend on the nature, proportion and compatibility of the components of the composite materials. In this paper we have conducted an ana...

A polyaniline-based conducting composite was prepared by oxidative polymerisation of aniline in a polyvinylchloride (PVC) matrix. The coherent free standing thin films of the composite were prepared by a solution casting method. The polyvinyl chloride-polyaniline composites exposed to 120 MeV ions of silicon with total ion fluence ranging from 10 to 10 ions/cm, were observed to be more sensitiv...

A composite gel composed of a water-soluble aromatic polyamide hydrogelator and the nanosheet Laponite®, a synthetic layered silicate, was produced and found to exhibit thixotropic behaviour. Whereas the composite gel contains the gelator at the same concentration as the molecular gel made by the gelator only, the composite gel becomes a softer thixotropic gel compared to the molecular gel made...
