제목 Enhancement of electroconductivity of polyaniline/graphene oxide nanocomposites through in-situ emulsion polymerization
초록 This study introduces a systematic approach to disperse graphene oxide (GO) during emulsion polymerization of Polyaniline (PANI) to form nanocomposites with improved electrical conductivities. The polymerization process was carried out in the presence of a functionalized protonic acid such as dodecyl benzene sulfonic acid (DBSA), which acts both as an emulsifier and protonating agent. The microstructures of the PANI/GO nanocomposites were studied by SEM; TEM; X-Ray diffraction; UV-Vis spectrometry; Fourier transform infrared and Thermogravimetric analyses. Meanwhile, the electrical conductivities of the nanocomposite pellets pressed at different applied pressures were determined using the four probe analyzer. The addition of GO was essential component to improve the thermal stability and electrical conductivities of the PANI/GO nanocomposites. An enhanced conductivity of 474 S/m was observed at 5 wt. % GO loading and applied pressure of 6 tons.
