Using di-ethoxy-silicane as precursor, a colloidal prepolymer was developed from sol-gel process. With silica colloid as modifier, the modified moisture-resistant films were prepared on neodymium-doped phosphate glass by spin coating. When the mole ratio of di-ethoxy-silicane to silica was 1∶1, the films after cure had improved abrasion-resistance. RMS was 1.245 nm, while laser-damage threshold value more than 15 J/cm2 at the condition of 1 053 nm, 1 ns. After staying in a closed circumstance at 80 ℃ and 95%RH, the films had approximately constant transmission and contact angle. It indicates that the films have a stable hydrophobic structure, good moisture-resistance, improved abrasion-resistant feature and longer service life.
