Effect of TiO₂ Nanoparticles on Cellulose Acetate Microporous Membrane Performance

Abstract:

The hydrophilic and mechanical strength of the cellulose acetate microporous membrane (CAMM) were improved by dealt with TiO₂ nanoparticles, which were obtained by adding a super dispersant into TiO₂-aqueous dispersion. The influence of such factors as temperature, processing time and TiO₂ concentration on adsorption amount of CAMM were investigated. The experiment data indicated that water flux of the modified CAMM increased with the increase of the TiO₂ adsorption amount. It suggested that hydrophilic of the CAMM was improved than that of blank. Experiments data also showed that the modified CAMM was better in mechanical strength but was weaker in elastic deformation than those of the blank. Water flux stability of the modified CAMM has improved significantly. Better modified conditions are as follows:TiO₂concentration 0.1mol·L^-1,temperature 35°C, processing time 6h, and adsorption amount 9.708mg/g.
