Synthesis and characterization of laser irradiated polyaniline/rice husk (silica) nanocomposites for electrical conductivity applications

Polymer nanocomposites contain inorganic fillers that have metallic particles dispersed in polymer matrices. These are very appealing for optical and electrical conductivity applications. Polyaniline/ silica (rice husk ash CCl (SiO2)), nanocomposites (PANI/RHACCl (SiO2)) nanocomposites can be manipu...
