Presents a review of the scientific literature on various methods for producing electrically conductive polymer materials and coatings. The prospects of using carbon nanotubes (CNT) to impart high electrical properties to the surface of materials are shown. The mechanism of formation of the structured surface of polymer materials with CNT is described. It is shown that the use of CNT is a promising way to impart electrically conductive and superhydrophobic properties to the surface.

Our living environment is full of diverse electronic products, making conductive polymer a popular subject for researchers. Insulating polypropylene (PP) can be improved in terms of conductivity by intermingling with electroconductive materials. Carbon black and carbon fiber are two materials that can supplement electroconductive and mechanical properties in insulating polymer materials. In this study, natural coir is first alkali-treated and then melt-blended with PP and carbon black, forming the composite. The resulting composite is tested in terms of its electromagnetic shielding effectiveness and mechanical properties. According to the results, when the amount of carbon black is 12 wt% and coir 3 wt%, the composite displays the optimum electromagnetic shielding of -23.56 dB, tensile strength of 37.07 MPa, and flexural strength of 47.21 MPa.

In the recent years a remarkable development can be observed in the electronics. New products of electronic industry generate more and more heat. To dissipate this heat, thermally conductive polymers offer new possibilities. The goal of this work was to develop a novel polymer based material, which has a good thermal conduction. The main purpose during the development was that this material can be processed easily with injection molding. To eliminate the weaknesses of the traditional conductive composites low-melting-point alloy was applied as filler. Furthermore in this work the effect of the filler content on thermal conductivity, on structure and on mechanical properties was investigated.

Conductive Polymers are one of the interesting topics to be developed in recent years. Conductive polymers can combine the properties of polymers and the electrical properties of metals. Research related to the electrical properties of conductive polymers, including electrical conductivity measurements and determination of activation energy has been carried out. This study aims to determine the effect of addition mass fraction of activated carbon into the nylon polymer on the conductive polymer material based on the electrical conductivity and activation energy. The variations of activated carbon used are 0%, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10% (wt/V). The conductive polymer from nylon polymer and activated carbon is made by casting solution method. The electrical conductivity measurement of the conductive polymer and the activation energy was carried out using the parallel plate method. The value of electrical conductivity increased from 5.62×10-9 ± 1.89×10-10 S/cm for the pure nylon to 2.51×10-8 ± 2.87×10-10 S/cm for the addition of mass fraction of activated carbon 8% wt/V. Meanwhile, there was a decrease in the addition of 9% wt/V and 10% wt/V of mass fraction of activated carbon, which were 2.36×10-8 ± 3.47×10-10 S/cm and 2.28×10-8 ± 4.01×10-10 S/cm. The activation energy of conductive polymer obtained decreased with increasing in the mass fraction of the activated carbon into the nylon polymer. The activation energy for the pure nylon was 0.0189 eV and 0.0127 eV for the addition of 8% wt/V mass fraction of activated carbon. Meanwhile, there was an increase in the addition of 9% wt/V and 10% wt/V mass fractions of activated carbon of 0.0145 eV and 0.0150 eV, respectively.
