Facile Route to Nature Inspired Hydrophobic Surface Modification of Phosphate Glass Using Polyhedral Oligomeric Silsesquioxane with Improved Properties

Creating water-repellent surfaces is essential in various sectors, from waterproofing to advanced electronics. A team has innovatively enhanced the hydrophobicity of a material known as tin fluorophosphate glass (Pglass). By utilizing hydrophobic polyhedral oligomeric silsesquioxane (POSS) coatings and leveraging Pglass’s unique low glass transition temperature, they’ve crafted a surface that resists water, potentially safeguarding metals and electronics from corrosion and shorts. This breakthrough melds low surface energy materials with specific surface roughness, aligning with the Cassie model of trapped air, fostering superhydrophobicity.
