Abstract

Interaction of mineral talc as an inert carrier with bioactive species (salicylic acid, glycerol, olive oil) in a mechanochemical process was studied by FTIR spectroscopy. Reaction of the talc silicate hydroxyls with carboxyl or alcohol moieties was observed for all the species studied. Dispersed layered composites, built from the silicate (talc) matrix, to which a bioactive component is bound, are formed in this interaction on the time scale of 1–5 min. The formation of new materials viz. layered dispersed mechano-composites proceeds due to etherification or esterification of the active sites on the silicate surface with acids or alcohols.
