Abstract Antireflective films with self-cleaning and abrasion-resistance properties show good performance in outdoor contaminated environments. In this paper, hollow rod-like MgF 2 sol was synthesized using the solvothermal method and 50 nm SiO 2 particle sol was prepared using the Stober method. The SiO 2 -MgF 2 mixed sol was prepared by adjusting the zeta potential of the two sols, and then the SiO 2 -MgF 2 mixed films were coated on the glass using the dip-coating method. The maximum transmittance was 99.4% and the average transmittance was 97.5% in 400–800 nm wavelength regions. After the films were modified by n-hexadecyltrimethoxysilane (HDTMOS), the contact angle reached 150.2°, and the pencil hardness reached 4–5 H. In this way, the multi-functional antireflective films were endowed with significant practical value.
