- Abstract
By using the hydrolysis of Al3+ salt under near-neutral conditions, Al(OH)3 colloidal solution has been prepared. The polypropylene based ultrafiltration (UF) membrane materials were uniformly coated with Al(OH)3 colloid via hydraulic spin coating technique. It was indicated that the degree of hydrophobicity of membrane increases with the extension of coating time. The surface of polypropylene membrane with colloidal structure was analyzed by scanning electron microscopy, infrared spectroscopy and field emission scanning electron microscope. Samples characterization with the aid of Fourier transform infrared spectroscopy (FTIR) found that the interaction between colloidal coating and PP membrane is due to the physical force. It was shown that nano-particles are formed on the surface, which increases the surface area and thereby increases the hydrophobicity behavior of the samples.
