text: Mica-titania pearlescent pigments (MTs) were previously coated with organic
molecules to obtain combination pigments (CPs) for achieving certain improvements
or functionalities. Anthocyanins (ACNs) are molecules that can be extracted from
natural resources and exhibit color changes via pH modifications of the enclosing
medium. The purpose of the study was to produce a new series of CPs by depositing
ACNs on MTs at different pH values, to observe the changes in color, and to associate
these changes to thermogravimetrically determined deposition efficiencies in light
of spectral differences. The extraction and deposition methods were based on aqueous
chemistry and were straightforward. The ACN deposition generally increased with
increasing pH and correlated with the consistency between the charges of the MT
surfaces and the dominant ACN species at a specific pH value. The fluorescence
of the CPs was inversely correlated with the deposition quantities invoking the
possibility of a quenching effect.
