The research activity presented in this paper is intended to investigating of certain valuable nanosized blue pigment ( P Bl 15:3) prepared by 3-way synthesis (functionalization reactions) and conditionin(dispersing with or without encapsulation), namely obtaining stable aqueous dispersions of blue pigment with modified surface used in medium nonspecific for pigments. The techniques employed to characterize the structure and properties of blue pigment dispersions with functionalized particles

... mpared to the original powder product were characterized by Fourier transform infrared spectroscopy FT-IR, thermogravimetric analysis (TGA), elemental analysis (EA) and particle size distribution (the distribution and average of particle diameter).In our finding the nano-dispersions obtained contain functionalized blue pigment particles with or without encapsulation in the form of liposomes with the average diameter below 200-300 nm, representing good results.
