摘要：
A λ∕4–λ∕4 broadband antireflective(AR) coating is developed with a sol-gel dip-coating method. By adding SAR-5 organosilicon resin into a base-catalyzed silica sol top layer and treating at 300°C, a broadband AR coating used for blast shields with a high average transmission of 99.34%(450–950 nm) and good hydrophobicity(with a water-contact angle of 119°) was obtained. After being subjected to rubbing 50 times and being maintained at a relative humidity of around 95% for 50 days, the average transmission of the coating decreased by0.29% and 0.04%, respectively. This indicates that the organically modified silica(ORMOSIL) broadband AR coating has good abrasion resistance and humidity stability.
