Influence of Polymer Additive on Synthesis of ZnO Nanoparticle by Precipitation Method

Abstract:

The effects of polyacrylic acid (PAA) as an additive on ZnO nanoparticles synthesized by precipitation method is investigated. It is found that ZnO synthesized exhibits a crystalline structure with hexagonal structure of the wurtzite. Primary size of ZnO nanoparticles synthesized can be controlled by PAA concentrations. Increasing of PAA concentration provide small particle size. Addition of 1 wt% PAA can be obtained the average primary size around 20 nm. Additionally, ZnO synthesized using PAA exhibits zeta potential value higher than ZnO synthesized without PAA. With the increasing PAA concentration, Zeta potential value increase. It indicates that ZnO synthesized using 0.5-1 wt% PAA can be well-dispersed in aqueous system and promote highly stable suspension.
