Performance Research of PVA (Polyvinyl alcohol) Based on HKUST-1 as Additive

We report a 98.8% UV light barrier, water resistant and better mechanical performance PVA membrane based on 5% HKUST-1 as UV protection additive, and compared with ZnO and UV 531. X-ray photoelectron spectroscopy (XPS) revealed binding energy decrease of Cu 2p3/2 and Cu 2p1/2, to be 1.2 eV and 1.4 e...

Zusammenfassung:We report a 98.8% UV light barrier, water resistant and better mechanical performance PVA membrane based on 5% HKUST-1 as UV protection additive, and compared with ZnO and UV 531. X-ray photoelectron spectroscopy (XPS) revealed binding energy decrease of Cu 2p3/2 and Cu 2p1/2, to be 1.2 eV and 1.4 eV, respectively, which indicates Cu2+ partially converted to Cu+ in the presence of residual C in PVA during UV irradiating, very different from that of ZnO which can be ascribed to diffused reflection.
