✦ Synopsis

In order to improve the mechanical properties of polypropylene (PP)/Al(OH) 3 composites, the surface of Al(OH) 3 was treated with a KH-792 silane coupling agent, and acrylic acid (AA) was grafted onto the PP. The interface between the PP-g-AA (PP grafted by AA) and silane coupling agent, and the interface between the Al(OH) 3 and silane coupling agent were investigated by x-ray photoelectron spectroscopy (XPS). The results show that the siloxane group of the KH-792 coupling agent can bond chemically with the Al(OH) 3 surface, and the amine group at the other site of the coupling agent can bond chemically with the acrylic acid of PP-g-AA. The mechanical properties of PP/Al(OH) 3 composites were significantly improved in high loadings.
