In this study, various dispersing agents were added to the suspensions of titanium dioxide nanoparticles for stability analysis, among which TWEEN® 80 improves the stability of suspension to the greatest extent. The study also shows that the optimal concentration of TWEEN® 80 is 1.0 wt%, based on the known results.
