“…This allows obtaining a conductive material with a strength enough for constructional applications for aircraft industry. Although one can find similar solutions of conducting/dielectric polymeric mixtures [35][36][37][38], none of them were dedicated for effective LSP solutions in aircraft. Moreover, multidisciplinary structured approach to the problem which includes advanced modelling of appropriate percolation systems with use of experimentally determined material properties, analytical and numerical thermo-electro-mechanical simulations of material behavior in various in-service conditions and during the lightning strike and further models updating will allow achieving and manufacturing of optimized material for LSP applications.…”

This work focuses on the elaboration and characterization of conducting polymer composites based on polyaniline (PANI) dispersed in an epoxy resin (ER) matrix and cured using an anhydride without a catalyst. PANI-doped benzene sulfonic acid was successfully synthesized in this manner and used as conducting filler. The effect of heating rate and PANI loading level on the curing process was investigated by differential scanning calorimetry in the dynamic mode. Furthermore, the phase structure, viscoelastic behavior and hardness of the composites were explored by dynamic mechanical thermal analysis and Vickers tests. The structure and morphology of the samples were investigated by scanning electron microscopy, which revealed behavior that varied as a function of the concentration of PANI in the composites. Dielectric properties were investigated up to 1 MHz. The electromagnetic shielding effectiveness of the composites was measured in the microwave band from 8 to 18 GHz. It was found that the electrical properties of PANI were influenced by elevated curing temperature of the ER, a variable that significantly affected the composite characteristics. In addition, the dielectric properties, curing parameters, viscoelasticites and electromagnetic behaviors of the composites were affecting by increasing the concentration of PANI filler in the matrix.

“…The specimens were prepared by several methods. The first method is that the specimens are prepared by brittle fracturing under liquid nitrogen and then sputtered with a very thin gold layer 11,19,20 . The second method is that the specimens are prepared by brittle fracturing under liquid nitrogen and are not sputtered with a thin gold layer.…”

The article presents results of studies on composites made from poly(propylene) (PP) modified with poly(aniline) (PANI) doped with dodecylbenzene sulfonic acid (DBSA) and chlorinated poly(propylene) (CPP). The volume resistivity of PP/CPP/PANI composites was detected, and the results show that the volume resistivity decreases with increasing CPP content, and there exists a minimum volume resistivity. Effects of CPP on the microstructure and crystalline structure of the PP/CPP/PANI composites and the relationship between the effects and the electric property were carefully analyzed by scanning electron microscope (SEM) and wide angle X-ray diffraction (WAXD). The method that the specimens of SEM are polished is appropriate to investigate the morphology of conducting polymer composites. The obtained results illuminate that the area of conducting parts and insulating parts obtained from the digital analysis of the SEM image is obviously influenced by the CPP content, the parameters of the lamellar-like structure are immediately related to CPP content and denote the dispersion of PANI-DBSA, and the percent crystallinity and mean crystal size of PP are directly correlated with the CPP content. The increasing area of conducting parts, the increasement of layer distance, the decreasement of size and layer number of the lamellar-like structure of PANI-DBSA, and the increasement of the percent crystallinity and mean crystal size of PP are beneficial to the improvement of the conductive property of PP/CPP/PANI composites.
