A series of high performance nanocomposite adhesives used for the nonpolar polyolefin films were synthesized. The effects of contents of nano-SiO2 and HFBMA on the properties of SiO2/FWPU nanocomposite adhesive were investigated by the static contact angle measurement,X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), thermogravimetric analysis (TGA) and tensile test machine. Relationship between adhesion strength and properties of nanocomposite adhesive was investigated. It proved that the wetting behavior, water resistance and thermal stability of nanocomposite adhesive had effect on the adhesion of the nanocomposite adhesive for low surface energy materials. And an empirical equation, 45 . 0 08 . 8 04 . 32 S L e T ? ? ? ? ? ? ,revealing the relationship among adhesion strength(T), surface tension of adhesive (γL)and the surface energy of adhered substrate (γS )was obtained. This empirical equation is helpful for predicting the adhesion strength.
