摘要：
Diblock copolymer brushes of polystyrene and poly (4-vinylpyridine) (PS-b-P4-VP) were synthesized by sequential monomers addition to a monolayer of 3-methacryloxypropyltrimeth-oxysilane. The diblock brushes were characterized by X-ray Photoelectron Spectroscopy (XPS) and Atomic Force Microscope (AFM). The results suggested that the 3-methacryloxypropyltrimeth-oxysilane initiator layer grafted on the silicon surface and the PS-b-P4-VP chains were covalently anchored onto the Si/SiO2/3-MPS surface.
