Abstract
Phosphoric acid treatments were conducted to improve the adhesion property of polyketone film to rubber. The effects of phosphoric acid treatments were characterized by using a contact angle analyzer and a XPS (X-ray photoelectron spectroscopy). Morphological changes were observed by using a scanning electron microscope (SEM) and an atomic force microscope (AFM) as the acid treatment condition varied in concentration and time. The contact angle was found to significantly decrease with the acid treatment. According to the XPS, increased wettability was attributed to the inclusion of oxygen containing groups such as hydroxyl, carbonyl and carboxyl by acid treatments. Cracks and pores were produced on the polyketone film surface and thus, roughness increased with the acid treatment. Interfacial adhesion strength between polyketone and natural rubber was largely improved by acid treatment due to the increased wettability and roughness of the polyketone surface. However, the higher level of acid treatment caused the degradation of the polyketone surface, and thus, its interfacial adhesion consequently decreased.
