On the Processes of the Charge Transfer in the Electrical Conducting Polymer Materials

The analysis of charge transfer processes in the electrical conducting solid polymer systems has been carried out. The processes in these systems are divided to two types. The first type is the process of charge transfer between electrodes and particles while the second one – the process of the charge transfer between conductive particles. The description of medium is carried out using Green temperature functions of polarization operators for the molecular medium. It permits taking into account the effects of frequency and space dispersion.

Polymer Composites on the Basis of Epoxy Resin with Mineral Fillers Modified by Tetraetoxysilane

Ultimate strength, softening temperature, and water absorption of the polymer composites based on epoxy resin (type ED-20) with unmodified and/or modified by tetraethoxysilane (TEOS) minerals diatomite and andesite are described. Comparison of experimental results obtained for investigated composites shows that the ones containing modified filler have better technical parameters mentioned above than composites with unmodified filler at corresponding loading.

Preparation and Characterization of Compounds Based on Poly(hydroxymethylacrylamide) and Post-consumer Polypropylene

In this work, in order to obtain materials with potential for treatment of water from oil industry, polymer composites were synthesized by polymerization reaction via free radical using n-hydroxymethyl acrylamide (HMAA) in the presence of post-consumer polypropylene (PP) with subsequent condensation reaction catalyzed by heating, which avoids the use of crosslinking agents. The products were characterized by Fourier transform infrared spectroscopy (FT-IR), optical microscopy (OM), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and X-ray diffraction (XRD).

Antioxidant traits of some nanocarbon moieties integrated in polymer materials (a Review)

This review briefly gives the status of worldwide researches in the aspect of an impact of incorporated fullerenes and carbon nanotubes (CNTs) on durability of different polymeric composites under stressful harsh therm-oxidative conditions. It has been inferred that among various nanoparticulates, fullerenes and CNTs are preferable to be used for enhancing thermal and mechanical properties of polymers.
