Abstract
In this study we report a simple method which via modifiedcolloid silica blending with polybutadienebase 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 1501o 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
