Optimization of Conditions for Nanocrystal ZnO in-situ Growing on SiO^sub 2^-Coated Cotton Fabric

摘要

Nano ZnO crystal in-situ growth onnSiO2 nano sol-coated cotton fabric via a reactionnbetween Zn(NO3)2 and (CH2)6N4 through a lowtemperaturenhydrothermal method was studied.nThe effects of hydrothermal reaction conditionsnand SiO2 nano sol coating on the size and crystallinenperfection of nano ZnO, and the UV protectionnproperty of the fabric were investigated. Thenoptimal treatment conditions for the highest Znncontent and the best ZnO crystalline perfectionnon the fabric surface were obtained. Under optimalnconditions, the cotton fabric was covered withn25 to 30 nm diameter ZnO crystallites and had annexcellent UV-blocking property.
