Photocatalysis - Anti-soiling chemical activity using adsorbed organics under solid/solid conditions - Part 2: Simulated weathering conditions cen:proj:35537

Scope

The scope of the item involves the methods of measuring the capacity of photocatalytic materials, both in form of films, paints, conglomerates or solid mixtures to self-clean toward a model soiling mixture deposited on their surface under the action of both light and water. The formulation of the soiling mixture would contain soot to simulate carbonaceous airborne particulate matter for a clear substrate or a suitable white pigment for dark substrate, and a model polymer to simulate natural airborne organic matter condensation. Transparent substrates like glass are excluded.
