摘要： 用X射线光电子能谱(XPS)研究铝板/聚丙烯层状复合材料的粘接界面相，提出了粘接界面的化学反应机制.研究发现,聚丙烯(PP)中加入马来酸酐接枝聚丙烯(PP-g-MAH)时，铝板面上Al 2p、O 1s谱线明显向高结合能端移动，表明PP-g-MAH与铝板表面发生了化学反应，形成Al－O－C配位键.配位键的形成使界面粘接强度明显提高. PP中不含PP-g-MAH时，铝板面上Al 2p、O 1s谱线处于低结合能端，聚丙烯未与铝板表面形成化学配位作用.

Abstract: Interphases at the adhesion bonded interfaces between aluminum sheet and polypropylene(PP)/and PP blended with maleic anhydride grafted polypropylene(PP-g-MAH) were studied by X-ray photoelectron spectroscopy (XPS), and a mechanism of coordination bonding at the interfaces was proposed. Compared to PP, for PP with addition of PP-g-MAH the spectra of Al 2p and O 1s at the surface of aluminum sheet shift to higher binding energy obviously, which indicates that chemical interaction between PP-g-MAH and surface of the aluminum sheet occurs, and as a result Al－O－C bond is formed. There is no chemical interaction between PP and surface of the aluminum sheet. The obvious improvement of the adhesion strength between aluminum sheet and PP with PP-g-MAH could be attributed to the formation of Al－O－C bonds.
