Abstract

Abstract

En 中文
• Mechanical conditioning coupled with controlled pyrolysis. • Evaluation of PVDF and organic residue removal by advanced techniques. • XPS provided direct evidence of fluorine redistribution after pyrolysis. • Cryogenic grinding increased PVDF degradation compared with dry grinding. • Surface fluorocarbon species from PVDF were significantly reduced after treatment.
