摘要：

Quaternary ammonium poly(ionic liquid) brushes have successfully been grafted onto silicon surface by surface initiation reverse atom transfer radical polymerization with CuCl2/Bpy/AIBN catalytic system.Surface properties of the polymer film and the polymer molecular weight are characterized by the ellipsometry,static water contact angle measurement,Fourier transform infrared spectroscopy attenuated(ATR-FTIR),X-ray photoelectron spectroscopy(XPS),atomic force microscope(AFM)and laser light scattering spectrometer.The results show that the wettability of the surface of poly(ionic liquid) films is closely related to the type of ionic liquids and length of the substitutes.
