摘 要：<正>The interface reaction between ultraviolet irradiated polypropylene （UV-PP） and an amino silane coupling agent, Y-aminopropyltrimethoxysilane （Y-APS） adsorbed on glass fibers has been investigated by means of the combining use of solvent extraction and FTIR as well as XPS. First, polypropylene （PP） physisorbed on the glass fibers surface was removed by the solvent extraction in order to minimize the effect of the PP siginal in FTIR and XPS analyses. Second, the remaining glass fibers after solvent extraction were analyzed by FTIR and XPS. The results show that the absorption bands of PP still exist in the FTIR spectrum and two new bands of N1s at 399. 6ev and 401. 6eV appear in the XPS spectrum for the composite with UV-PP and Y-APS treated glass fibers. Thus, the interface reaction between the UV-PP and Y-APS has been monitored directly. In addition, it may be concluded that OH and COOH groups of UV-PP form chemical bonds with NH2 group of Y-APS, respectively.
