Amphiphobic surfaces are being promisingly applied in numerous fundamental and industrial applications. A transparent amphiphobic coating was fabricated by combining fluoroalkyl silane copolymer (PFAS) with SiO 2 nanoparticles. Dodecafluoroheptylmethacrylate (DFMA) and γ‐methacryloxypropyltrimethoxysilane (γ‐MPS) were monomers, and PFAS was prepared via free‐radical polymerization. Tetraethoxysilane (TEOS) and SiO 2 nanoparticles were added in PFAS solution to obtain a homogeneous hybrid sol. The hybrid sol was coated on glass surfaces. After drying, a transparent and amphiphobic hybrid coating was obtained. The visible‐light transmittance of the hybrid coating on the glass surface ranged from 85% to 90%. The contact angle (CA) of the hybrid coating for water, ethylene glycol and hexadecane were 153°, 150°, 115°. The hybrid coating had a great thermal stability below 280 °C. The hardness and adhesion of the hybrid coating could reach 1 grade and H, respectively. This is expected to be a facile, cost‐effective method to obtain transparent amphiphobic surfaces.
