Synthesis and characterization of enhanced hydrophobic polysilazane coatings with high transparency and durability

Year: 2025

Type: article

Abstract: The development of transparent hydrophobic coatings with durability is crucial required both optical transparency and hydrophobic properties for application. In this study, a series of durable, transparent and hydrophobic coatings were prepared by dispersing hydrophobic fumed silica (SiO 2 ) in the fluorinated polysilazanes (FPSZ) matrix and then spraying the mixture onto microscope slides. The coating FPC-1 achieved excellent comprehensive performances showing a water contact angle of 125°, a transmittance of 88.9 % at 400 nm, a pencil hardness of 6H, and an adhesion class of 5B. In addition, the coating of FPC-1 could withstand chemical corrosion for 7 days and 100 cycles of abrasion without significant degradation. These coatings show has great potential for applications in transparent optical devices.
