摘要

Novel cationic spherical polyelectrolyte brushes(CSPB) consisting of γ-methacryloxypropyl trimethoxy-silane(KH-570) modified SiO_2 cores and poly(Dimethyl diallyl ammonium chloride) (PDMDAAC) brushes were prepared by conventional free radical polymerization. The resulting CSPB were characterized by Fourier transform infrared spectroscopy (FTIR), Transmission electron microscopy (TEM), Scanning electron microscopy (SEM), and Thermo-gravimetric analysis (TGA). After cleaving the polyelectrolyte chains from the anchoring surface, the molecular weight of brushes was 1.824×10~3 gmol~(-1) from Gel Permeation Chromatography (GPC) measurements.
