Leverage the environmentally friendly nanoparticles on the thermal stability and electrical conductivity of Polyp-Phenylenediamine

Manal Gamal Mohamed Ahmed

Eggshell is a biomaterial containing 95% by weight of calcium carbonate in the form of calcite and 5% by weight of oxides (Mn, Si, Al, Fe, Cr, Cu and Ca) and organic substances. Para-phenylenediamine was polymerized by oxidation in aqueous acidic solution with potassium persulfate as an oxidant. Poly (p-phenylenediamine) and their nanocomposites with nano eggshell, carbon nanotube and nano eggshell with carbon nanotube were prepared and compared with ground eggshell. All prepared samples were characterized using FT-IR, Raman and UV-spectra. The morphology has been studied by SEM and TEM. The thermal stability of the prepared polymer nanocomposites was analyzed using TGA, the results showed high thermal stability compared to the net polymer. The electrical conductivity properties were studied the results showed efficiency in the improvement of electrical properties, which form a better composite with higher conductivity, so can be used as a semiconductor.
