Surface and interface study of ZnO nanoparticlesmodified by octadecanol phosphate

Abstract

In this paper, we describe an effective method in which ZnO nanoparticles were prepared through the rapid precipitation transformation reaction in aqueous solution of ZnSO4 and NaOH with octadecanol phosphate (ODP) as a modifying agent. From the study on the surface and the interface, ZnO nanoparticles modified by ODP exhibited small size, pore structure, good dispersion, and hydrophobicity. The wide variety of surface wettability can be achieved by changing the preparation parameters. The research offers a simple and effective approach to prepare ZnO filler inmild condition and enhances interfacial compatibility between ZnO powders and matrixes by treating the surface with certain capping molecules.
