Innovative Building Materials Shaping the Future of Architecture




For application to glass, steel, paper, and other materials, a new coating from researchers at the University College London resists moisture even after being scratched or exposed to oil—typical weak spots for conventional repellent coatings. Made from coated titanium dioxide nanoparticles, the finish rejects water, oil, and even red wine by bouncing the invasive substances off its surface and removing dirt in the process. Although the coating is currently applied in 20-centimeter-square areas, “we see no reason why this couldn’t be scaled up,” says Ivan Parkin, head of the university’s chemistry department and corresponding author of a paper on the research in the journal Science. Parkin’s team has talked about automobile paint and moisture-resistant coatings as possible applications for the technology. It could eventually be used to create a durable, self-cleaning façade that can better withstand the elements than current options on the market
