Abstract

Zinc (II) oxide micrometer (300 nm) and nano particles (100 nm) were synthesized in different glycols and were used for the preparation of ZnO/poly(methyl methacrylate) nanocomposites. Very low concentrations of zinc oxide quantitatively absorb UV light in the region between 290 and 380 nm. Besides having extraordinary UV absorption properties, nano zinc oxide also substantially enhances the stability towards sunlight as well as thermal stability of resulting nanocomposites. On the other hand, submicrometer ZnO is less effective UV absorber and thermal stabilizer than nano ZnO.
