Eco efficient thermo ultrasonic recycling of pet for cost effective electromagnetic shielding applications (opens in new tab)

The research introduces a cost-efficient strategy for developing an electromagnetic interference shielding composite entirely derived from recycled polyethylene terephthalate (PET) serving simultaneously as matrix and filler source. Porous carbon (POC) was synthesized from waste PET and incorporated into a PET matrix at various loadings (3, 5, 8, 15, 20, and 30 wt%) through an innovative thermo-ultrasonic technique (TUT). This hybrid processing approach couple’s polymer melting with ultrasoni...
