Dispersion of Manganese Dioxide Particles Using Anionic Technol PG and Sodium Cholate in the Preparation for Application as Films on Substrates

Abstract

Manganese dioxide (MnO2) is widely used in cosmetics and self-cleaning materials because of the high refractive index and photocatalytic activity of this compound. In the present work, the surfaces of MnO2 particles were coated with a commercially available anionic phospholipid mixture, Technol PG, and sodium cholate(SC). These coated particles were readily dispersed in water and subsequently applied as films onto glass substrates by drop-casting.
