Abstract
To improve the photooxidation degradation resistance and antimicrobial ability of ZnOfilled polypropylene random copolymer PPR 13X zeolite particles supported with nanoZnO with different morphologies were prepared and used to manufacture filled PPR composites The formation of ZnO with different morphologies on the surface of 13X zeolite was proved by atomic absorption spectroscopy scanning electron microscope UV–vis spectra and fluorescence spectra The results indicated that the photooxidation degradation resistance of nanoZnOsupported 13X zeolitefilled PPR composites is higher than that of PPR composites filled by the same content of pure nanoZnO Antimicrobial experiment results show that nanoZnOsupported 13X zeolitefilled PPR composites exhibit higher antimicrobial properties than ZnOfilled PPR composites prepared by directly adding nanoZnO into PPR matrix for Staphylococcus aureus and Escherichia coli The addition of nanoZnOsupported 13X zeolite particles increases the crystallization temperature but has no influence on the melting behavior of PPR compositesThe project was supported by the Natural Science Foundation of China Grant No 51173208 51373202 and Natural Science Foundation of Guangdong Grant No S2011020001212 The authors wish to acknowledge Prof Ma Lin for supplying the devices for antibacterial experiments
