Synthesis and Characterization of Polyaniline Nanofibres by Rapid Liquid-Liquid Interfacial Polymerization Method

Inherently conducting polymer polyaniline (Pani) has been synthesized by a novel interfacial polymerization technique using trichloroethane as organic media. Ammonium peroxydisulphate was used as an oxidizing agent dissolved in aqueous media. The synthesized polymer was subjected to the physico-chemical characterization by UV-Vis and FT-IR Spectroscopy and Scanning Electron Microscopy. From the SEM Micrographs it was observed that interfacial polymerization offers the fibrillar type of morphology having 200 nm sized fibers.

Some Properties of Elastomeric Compositions with High-disperse Carbon Additives

The influence of a carbon nanomaterial obtained in a high-voltage discharge plasma on the endurance of elastomer compositions has been investigated. Complex tests of elastomeric compositions with highly dispersed carbon additives allowed us to confirm the model of nonlinear elastic deformation of macromolecules and adhesion between the elastomer and the nanoparticles.
