The PVF Foam is a kind of soft and good flexibility material in the humid environment. The structure of PVF Foam belongs to high density and its pores are very small, and also called as the high density foam. According to customer requirement, these porous products are always cut into different sizes. It can be adopted to clean semi-conductor wafer in the post-CMP process, or used as the cleaning sponge on the car and kitchen market. In order to make the PVF Foam to be more wear-resistant, the nano-sized aluminum oxide is intended to bridge into the PVA matrix in the present research, at which silane is also added to serve as the coupling agent. The present research focuses on the change of the hydrolysis structure of the aluminum oxide which pH dependent. The coupling effect performed by the silane to bridge PVA with aluminum oxide is confirmed by the analyses of NMR, FTIR, XRD, EDS and ICP-MS. The physical properties of the present PVF products are also verified by SEM, TGA, DSC and Instron. The present results prove that the aluminum oxide can be bonded with PVA efficiently through the help of the added silane.
