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.
