| 英文摘要 | A radical chain-transfer polymerization technique has been applied to graft-polymerize brushes of polystyrene (pst) on single-crystal silicon substrates. 3-mercapto-propyltrimethoxysilane (mptms), as a chain-transfer agent for grafting, was immobilized on the silicon surface by a self-assembling process. the structure and morphology of the graft-functionalized silicon surfaces were characterized by the means of contact-angle measurement, ellipsometric thickness measurement, fourier transformation infrared (ftir) spectroscopy, and atomic force microscopy (afm). the nanotribological and micromechanical properties of the as-prepared polymer brush films were investigated by frictional force microscopy (ffm), force-volume analysis and scratch test. the results indicate that the friction properties of the grafted polymer films can be improved significantly by the treatment of toluene, and the chemically bonded polystyrene film exhibits superior scratch resistance behavior compared with the spin-coated polystyrene film. the resultant polystyrene brush film is expected to develop as a potential lubrication coating for microelectromechanical systems (mems).
