We have studied the effects of using a composite fabricated from carbon nanotubes and a host polymer, poly~m-phenylene-vinylene-co-2,5-dioctyloxy-p-phenylene-vinylene! ~PmPV!, as an electron-transport layer in organic light-emitting diodes. Double layer devices using this composite as an electron-transport layer, triple layer devices with a composite electron-transport layer, and poly~9-vinylca...

Chemiresistor sensors made from carbon black – polyisobutylene composite, perform based on the change of the resistivity of the composite when they swell in the analytes. Two models are necessary to describe the mechanism of carbon-polymer chemiresistors theoretically: the conductivity model and the thermodynamic model. In this work, the conductivity model was studied. Sixty-four chemiresistors...

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...
