The article investigates the effect of thermal modification of porous carbon material (PCM), obtained from plant feedstock, on its morphology and fractal structure by small-angle X-ray scattering (SAXS) method. The analysis of the scattering intensity curves serve the basis for calculating the parameters of the PCM porous structure: the Porod constant, the Porod invariant, average pore radius, specific surface area, and mass and surface fractal dimensions. It has been found out that the PCMs obtained have fractal structure, formed from mass and surface fractals, the sizes of which increase at the growth of temperature and modification time.PACS81.05.Uw; 61.05.cf; 82.47.Aa
Polyaniline/glauconite-silica (PАn / Gl-Si) composite were obtained by one-step in situ polymerization of aniline in the presence of microdispersion of natural mineral glauconite-silica. The physicochemical properties (phase content, thermal stability, conductivity and magnetization) of the produced samples of composites with different ratio of components have been studied. It was shown that the polymeric component stipulates the conductivity for the synthesized composite samples, while the mineral particles stipulate their magnetic properties and higher thermal stability in comparison with individual polyaniline. Besides, it was determined that participation of the surface of glauconite-silica microparticles in the process of aniline polymerization leads to considerable increasing of ordering of the polymer in the composite.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
