Nanopowders of barium titanate, surface active functional polymers, barium titanate suspensions stabilized by surface active oligomers in mediums of different polarity and in solution of polymer film former. Work aim: Elaboration of store technology and sick of medium for storage of nanodisperse powders. Elaboration of dispersion process of nanopowders in water and free water medium with the aim of obtaining of homogenous dispersions for technology of film forming and inject print. Investigation methods: Particle size was measured by light dispersion and transmission electron microscopy (TEM). Presence of polymer core on the surface of nanoparticles was suggested by IR spectroscopy with Furrier transmission. Polymer content on the surface was determined by the method of elemental analysis. Suspension stability was determined by light dispersion method. The most perspective surface active substances and the methods of surface modification were recommended. Dependence between adsorbed modifier quantity and sediment stability of nanoparticle suspension was established. Recommendations and methods were sent by customer.
