What are Some Common Types of Hydrophobic Coatings Used in Catalysis?
Several types of hydrophobic coatings are employed in catalytic applications:
1. Silane Coatings: Organosilanes are often used to create hydrophobic surfaces on catalysts. They form covalent bonds with the surface and produce a durable, water-repellent layer.
2. Fluorocarbon Coatings: These coatings consist of fluorinated compounds that provide excellent hydrophobicity and chemical resistance.
3. Polymer Coatings: Polymers such as polytetrafluoroethylene (PTFE) can be applied as a coating to impart hydrophobic properties to catalysts.
