Abstract Firstly, polystyrene (PS) microspheres (ca. 260 nm) were surface-modified with polyvinylpyrrolidone (PVP) via a soap-free emulsion polymerization method. Then core-shell composites of PS/MSiO2 with PS as core and mesoporous silica as shell materials were prepared via a synergistic self-assembly process of PVP surfactants and cetyltrimethylammonium bromide micelles. The results indicated that the silica shells were about 60 nm in thickness with radial meso- channels. The specific surface area of the composites and the average pore size of silica meso-channels were 848 g/m2 and 2.54 nm, respectively. The compressive elastic moduli (E) of the individual composite particle were assessed by analyzing the force-displacement curves, measured by scanning probe microscopy, on the basis of the Hertz contact model. The fitted and calculated E values were 4.47±0.83 (Poisson's ratio=0.33) and 4.89±0.89 GPa (Poisson's ratio=0.2), respectively. These results suggest that the improvement of the elastic response of organic/inorganic composite particles may be ascribed to the presence of mesoporous shells, indicating a potential application in optimizing the structural design of novel non-rigid composite abrasives.
