As the antireflective coating prepared by sol-gel method had poor environmental stability, sol-modified method was used to improve its performance. The alkaline silica sol was prepared in ethanol solvent by using tetraethyl orthosilicate (TEOS) as precursors and aqueous ammonia as catalyst (content ~ 28%). Polyethylene glycol (PEG200) was used to modify the silica sol and the antireflective (AR) coating was prepared by dip-coating from the modified sol. The transmittance, composition, refractive index, and hydrophobicity of AR coating were discussed by combining the spectrophotometer, FTIR, Coating Wizard 32 coating design software, optical microscopy imaging system and JC2000A static droplet contact angle measurement software. Finally, the environmental stability of the AR coating was tested. The results showed that AR coating transmittance decreased by less than 0.1% after UV light for 20 hours and its transmittance decreased by about 0.57% in the humid environment for 2 months. Resistance to environmental stability has been improved. 展开更多
