Effect of graphene nanoplatelets on structural, morphological, thermal, and electrical properties of recycled polypropylene/polyaniline nanocomposites

Recycled polypropylene/polyaniline/graphene nanoplatelets (rPP/PANI/GNPs) nanocomposites were fabricated via ultrasonic-assisted single-screw extruder at 150–170 °C with a rotating screw speed of 50 rpm. The ultrasonic wave frequency and power supply were kept constant at a frequency of 20 kHz and 6...
