Abstract: Polyurethane with double bonds was prepared by using hydroxylfluorosilicone oil and
pentaerythritoltriacrylate (PETA) as raw materials. Ultraviolet absorber (UVA400) and nanosilica particles
were added into the finishing solution to improve the UV protection and surface roughness of the coating.
Ultraviolet (UV) blocking and superhydrophobicity fabric coating was fabricated by UV light initiating double
bond radical polymerization. FTIR and SEM analysis showed that fluorosilane and PETA were introduced
into the polyurethane molecular chain. There were micro-nano-shaped projections on the surface of the
fabric, and the rough surface coating was constructed. Hydrophobic and UV protective tests of coated fabric
revealed that the coated fabric exhibited excellent superhydrophobicity and UV protection performance.
When mass fraction of SiO 2 and UVA400 was 15% and 1.5%, respectively, the coated fabric had a water
contact angle of 154°, roll angle of 9°, ultraviolet protection factor (UPF) value of 72, and the UV-ray
transmittance of coated fabric was 2.96% in the ultraviolet A(UV-A) band. After the coated fabric was
accelerated aging for 120 h, its contact angles was 155°, its UPF values was 117, its UV-ray transmittance
was 2.68% in the UV-A band, indicating that the coated fabric had excellent durability.
