Article Preview

Lanthanum (La) nano-films prepared by a self-assembled technique on a silicone-based material surface, was studied by using an all-round functional Turbiscan LAB stability analyzer and X-ray fluorescence analysis (XRF) as well as atomic force microscope (AFM). La content introduced in the assembled nano-film reached a maximum at pH value between 5 and 6. In the preparation of colloidal sol, no phase separation took place at 60 °C where the colloidal particles uniformly and stably dispersed in the solution. The optimum topographic feature was observed after 24 hours, whence self-assembled process was performed. The particle dispersion of the assembled film was uniform and compact at the optimum EDTA to La molar ratio 0.5.
