Self-Cleaning Photocatalytic Polyurethane Coatings Containing Modified C60 Fullerene Additives

Self-cleaning antireflective optical coatings.

Low-cost antireflection coatings (ARCs) on large optical surfaces are an ingredient-technology for high-performance solar cells. While nanoporous thin films that meet the zero-reflectance conditions on transparent substrates can be cheaply manufactured, their suitability for outdoor applications is limited by the lack of robustness and cleanability. Here, we present a simple method for the manu...

Photocatalytic and Self-Cleaning Properties of Ag-Doped TiO2

Commercially available TiO2 of anatase structure produced in the Chemical Factory Police S.A. was modified by doping Ag from AgNO3 solution via photodeposition method. The obtained amount of deposited Ag on TiO2 was in the range of 0.11 to 0.98 mass %. Deposition of Ag on TiO2 resulted in the retarding of the recombination reaction and formation of the higher amount of OH radicals on the photoc...

Photocatalytic Self Cleaning Textile Fibers by Coaxial Electrospinning

Photocatalytic self-cleaning textile fibers have been created using coaxial electrospinning. This is accomplished by electrospinning cellulose acetate as the core phase and a dispersion of nanocrystalline TiO2, a well-known photocatalyst, in the sheath phase. A simple deacetylation step after the initial electrospinning yields self-cleaning textile fibers. Self-cleaning activity is exhibited at...

A New Approach for Self-Cleaning Silicone-based Facade Coatings

Since being introduced in 1963, silicone resin emulsion paint (SREP) has developed into one of the most modern facade coating systems. While specific formulations and raw materials have changed in the last 42 years, the long-lasting performance properties resulting from the unique combination of water repellency, vapour permeability, low VOC and the silicon-resin based structure have remained c...
