Encapsulation of organic pigments for decorative photocatalytically active façade coatings [Elektronski vir]Švara Fabjan, Erika ...The damage of surfaces of various building objects due to exposure to harmful environmental factors can be reduced by photocatlaysis. The photocatalysts do not degrade just the organic dirt, but also ... organic constituents, for example organic pigments. The main goal in the present work has been to protect the organic pigment against photocatalysis by encapsulation. Detailed study on synthesis and influence of different parameters (temperature, pH) on silica encapsulation of model organic pigments was investigated. It is shown that thethickness, porosity and uniformity of silica shells (coatings) around individual pigment particles depend significantly on pH and temperature of synthesis. It is further demonstrated that the obtained silica shells can serve as an efficient protection against the highly reactive products of photocatalysis. The degree of protection depends not only on the thickness of silica shells but also on their porosity.Source: NICOM4 [Elektronski vir] ([6] str.)Type of material - conference contribution ; adult, seriousPublish date - 2012Language - englishCOBISS.SI-ID - 1899879
