Fabrication of Polystyrene-Encapsulated Nanodiamond via In Situ Latex Polymerization and their Wettability Evaluation
Nanodiamonds coated with polystyrene were prepared by in-situ latex polymerization using azobisisobutylonitrile as initiator in alcohol-water solution. The products were characterized by transmission electron microscope, X-ray diffraction, thermo-gravimetric and differential thermal analysis and Fourier transformation infrared spectrum. A possible formation mechanism and the structure of products were proposed. The experimental evaluation of wettability performance showed that the hydrophobicity of nanodiamond have been enhanced with the wrapping of polystyrene films on the surface of nanodiamond particles.
