  Abstract

Photocatalytic ZnO nanoparticles were synthesized through sonochemical synthesis process for depositing them onto PCM microcapsules for the purpose to provide warming ability and antibacterial activity to rubber sheets for diving suit. Spherical ZnO nanoparticles having average diameter of 50 nm could be synthesized in deionized water under ultrasonic irradiation for 30 min at pH 11.5. However, needle-like ZnO nanoparticles were obtained in ammonium hydroxide instead of deionized water as medium. It was found that spherical shape is more favorable for the sonochemical coating thereof onto PCM microcapsules. The formation of ZnO nanopartcles through Zn(OH)2 microparticles were confirmed using UV-Vis spectroscopy and X-ray diffractometry. Composite rubber sheets containing 0-25 wt% of PCM microcapsules with or without ZnO nanoparicles were prepared by solution casting. The composite rubber sheets exhibited much better warming ability compared than neat rubber sheet in cold water due to exothermic heat by PCM microcapsules. Moreover, The composite rubber sheets with ZnO nanoparicles showed excellent antibacterial activity against bacteria of S. aureus by showing 99.9 % reduction of bacteria.
