Abstract
En 中文
• PV backsheet PET shows atmosphere-dependent pyrolysis distinct from packaging PET. • CO2 and air lower PET activation energy and promote thermal decomposition. • TG-FTIR resolves the temperature-dependent release of key volatile species. • At 500 ℃, condensables reach 64.5%, with benzoic acid as the major product. • Crystalline PET converts into an amorphous porous carbon residue.
