AbstractWe report the successful application of bipolar electrochemistry for depositing metals and conducting polymer nano-structures on isolated template-grown carbon nanopipes (CVD-CNP). Metals such as tin, cobalt and nickel were reduced electrochemically at the tips of isolated CVD- CNP from their chloride or nitrate salts. Polypyrrole dendrites could also be grown on both ends of selected CVD-CNP. The potential applications of thus encapsulated CVD-CNP in nano- fluidics and other areas will be discussed.

We find that the ratio of dielectric permittivity to shear modulus is linearly related to the number of polar groups per polymer chain in polar dielectric elastomers (PDEs). Our discovery is verified via computational modeling and validated by experimental evidences. Based on the finding, we introduce the new concept of dielectric imperfection (DI) and provide some physical insights into understanding it through demonstrating the large nonlinear deformation of PDEs with DIs under electric fields. The results show remarkable DI-induced inhomogeneous deformation and indicate that the size and dielectric permittivity of DIs have a significant impact on the deformation stability of PDEs under electric fields. With this concept, we propose some potential applications of PDEs with DIs.

This review aims at reporting on interesting and potential aspects of conducting polymer/clay nanocomposites with regard to their preparation, characteristics and engineering applications. Various conducting polymers such as polyaniline, polypyrrole and copolyaniline are introduced and three different preparation methods of synthesizing conducting polymer/clay nanocomposites are being emphasized. Morphological features, structure characteristics and thermal degradation behavior are explained based on SEM/TEM images, XRD pattern analyses and TGA/DSC graphs, respectively. Attentions are also being paid on conductive/magnetic performances as well as two potential applications in anti-corrosion coating and electrorheological (ER) fluids.

AbstractPreparations of hybrid composites composed of two conducting components, a conducting polymer and silver, are reviewed. They are produced mainly by the oxidation of aniline or pyrrole with silver ions. In another approach, polyaniline or polypyrrole are used for the reduction of silver ions to metallic silver. Other synthetic approaches are also reviewed. Products of oxidation of aniline derivatives, including phenylenediamines, are considered. Morphology of both the conducting polymers and the silver in composites displays a rich variety. Conductivity of the composites seldom exceeds 1000 S cm−1 and seems to be controlled by percolation. Interfacial effects are also discussed. Potential applications of hybrid composites are outlined; they are likely to extend especially to conducting inks, printed electronics, noble-metal recovery, antimicrobial materials, catalysts, and sensors.
