Mechanical And Thermal Properties Of Thermally Conductive Fillers Filled Polypropylene Composites

The current study was carried out to investigate the effect of various fillers for example (such as) carbon nanotube (MWNT), synthetic diamond (SD), boron nitride (BN) and copper (Cu) on the properties of polypropylene (PP) composites. This composite was compounded using two roll mill mixing method...
