摘要：
In this study, we report a simple method which via modified-colloid silica blending with polybutadiene-base polyurethane to form a hydrophobic composite material. The hydrophobic film is characterized by optical microscopy, scanning electron microscopy (SEM), and water contact angle. Desired surface roughness was obtained by hydrophobic silica tuning the microstructures that contact angle approach 150.1o when contain ODTMS/colloid silica =90/10. With the increase of the blended ratio of modified silica with the PBU, we also could obtain the rough surface, and increased its hydrophobicity.
