  Polymer Waste-Derived Activated Carbon from PET for High-Efficiency Supercapacitor Electrodes

  By Baburao Gaddala, Srinivas Ganganagunta, Abha Gupta, Gautam Prasad Dewangan, Jeyadevan S.

  Abstract: The exponential increase in plastic waste, particularly Polyethylene Terephthalate (PET)—a polymer characterized by its repeating aromatic terephthalate units and ester linkages—has escalated into a global environmental crisis. This study details a low-cost synthesis of porous carbon materials derived from waste PET via pyrolysis followed by chemical activation with calcium hydroxide (Ca(OH)2). During pyrolysis, the PET polymer chains undergo thermal degradation, where the aromatic rings in the backbone serve as precursors …
