▎ 摘　　要

NOVELTY - Preparing photocatalytic performance poly(m-phenyleneisophthalamide) (PMIA) mixed matrix film by blending comprises (i) synthesizing graphene oxide (GO)-zinc oxide (ZnO)-silver nanocomposites with photocatalytic properties by hydrothermal method, (ii) mixing GO-ZnO-Ag nanocomposite material obtained in step (i) with PMIA to prepare a casting solution, and (iii) preparing PMIA mixed matrix film by the non-solvent induced phase separation method of the casting solution obtained in step (ii). USE - The film is useful in catalytic degradation of methylene blue film (claimed). ADVANTAGE - The film: improves mechanical strength of the composite film; greatly enhances hydrophilicity; and has better anti methylene blue pollution ability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a PMIA mixed matrix film with photocatalytic performance prepared by the above mentioned method.
