Paper Abstract

A new method to strengthen nano porous broadband anti- reflectance silica films is described. Silica sols were made from TEOS with a base/acid two-step catalytic process. Properties of silica films deposited with a dip-coat method are characterized with AFM, SEM, spectrophotometer and abrasion test. Experimental results show that an average reflectance of a glass coated with the nano porous silica films is less than 1% in the visible region; and that the two-step catalysis obviously strengthens the films. Finally, the strengthening mechanism of the films is discussed.
