Abstract. The paper considers applications of foamed glassy phosphate materials as carriers of biologically active substances. The atomic layer deposition method allowed chemically synthesizing surface-modified composite materials based on graphite and carbon fibers, which maximally preserved the activity of enzymes and biologically active substances. The synthesis process of a mono-layer titanium-containing coating on the surface of graphite and carbon fibers by processing them with TiCl4 vapors is considered. The main characteristics of the graphite surface before and after modification and characteristics of the porous structure and surface of carbon fibers are obtained. Biologically active substances by adsorption from a solution to the surface of both the original and modified carriers were applied. biological activity and temperature stability of the obtained composite materials were studied. It is shown that the activity of a biologically active substance depends on the chemical composition and state of the surface of carbon-based carriers.

Active Substances

In the creation of new polymeric composite materials, the use of biologically active substances, e.g. the hydrolysis products of keratin-containing proteins of different structure, is promising. The possibility of using keratin hydrolysates as modifying additives for improving different properties of various elastomer composites is shown. These are vulcanising agents and vulcanisation accelerators for composite materials based on synthetic polyisoprene; secondary vulcanising agents for elastomer materials based on chlorine-containing rubbers; vulcanisation accelerators for composites. The use of these compounds makes it possible to remove from the composition of materials ecologically harmful components and ingredients that are produced from non-renewable sources of raw material, to solve a number of economic problems, associated, among other things, with the need for import replacement, and also to produce latex composites that in their properties approach latexes of natural rubber.

The paper attempted to produce geopolymer construction materials with improved biological resistance based on glass waste to create an alternative to cement. With the use of modern physical methods, processes of structure-forming of cementing substances based on sodium-potassium silicate glasses have been studied. It has been found that when the glass-absorbent binder-based composite materials are solidified, the complex alkaline composition is formed. Stability of developed materials under conditions of exposure to biologically active media was investigated. Potential mechanical devices of materials operated in rooms with different microclimates, provided by the production process, have been identified.
