Nanodiamond (ND) has versatile applications in electro-optical devices, sensors, and biomedicine. However, serious aggregation of ND has limited its further applications. After introduction some double bonds on the ND surface by treatment with acryloyl chloride (AC), ND-grafted-poly(styrene) (ND-PS) and ND-grafted-poly(methyl methacrylate) (ND-PMMA) having excellent solution dispersion were prepared via in situ free radical copolymerization with styrene (St) and methyl methacrylate (MMA) using the “grafting from” synthesis strategy. Both FTIR and Raman results reveal that the polymer chains are covalently attached to the ND surface and the ratio of grafted polymers was determined by TGA. Dynamic light scattering analysis, TEM images and contact angle analysis demonstrate that the dispersion, stability and hydrophobicity of ND have been significantly improved after modification with PS and PMMA.
