Silica nano-particles modified with polymer

The experience accumulated by the laboratory personnel in the field of directional change of surface properties allows one:

- to hydrophobize the surface, thus providing the materials with water repellent properties;

- to adjust the thixotropic characteristics and to structurize the appropriate dispersion media,

- including the formation of chemically cross-linked structures;

- to develop the multifunctional layers with different architecture and nature of active sites on the surface of nanoparticles;

- to obtain surfaces with conductive, redox, complexing, or catalytical properties;

- to provide the boundary layers with the desired sorption or complexing properties;

- to provide the controlled release of biologically active compounds from the carrier surface, their capsulation and stabilization;

- to decorate nanodispersed materials with nanoparticles of various nature.

Surface types:

- oxide inorganic;

- silicate materials;

- carbonaceous;

- polymers organic.

- metallic.

Carrier types:

- nanodispersed powders;

- granular powders;

- latexes or microspheres;

- films;

- fibers and monoliths.
