概要 Owing to their high chemical and thermal stability, fluoropolymers are used in a variety of industrial applications. For the use of fluoropolymers with high sustainability, the establishment of waste treatment technique should be required.Here we show efficient mineralization of perfluorinated ion-exchange membrane polymer, PVDF,ETFE,and VDF-based copolymers in subcritical water by a combination of either an oxidizing or a reducing agent. The effort to lowering reaction temperature and formation of CaF2 in the presence of stoichiometric amount of Ca(OH)2 are reported.
