The development of new direction in ISC of NAS of Ukraine connected with synthesis and investigation of functionalized polysiloxane xerogels is considered in the review. The contribution of Acad. of NAS of Ukraine A.A. Chuiko in becoming of this direction is shown. On the basis of activity of the research team created due his support the ways are considered of the synthesis (using sol-gel method) of new class of sorbents and carriers, namely: polysiloxane xerogels functionalized with nitrogen-, oxygen-, phosphorus- and sulfur-containing ligand groups. Using a number of physical methods (SEM, TEM, AFM, IR and Raman spectroscopy, 1Н, 13C, 29Si and 31P CP/MAS NMR, EPR spectroscopy, ERS, thermal analysis) the structures of the xerogels and their surfaces were justified. The influence of some factors on the structural-adsorption characteristics of such xerogels and their sorption properties is analyzed. The ways of preparation of the new materials such as polysiloxane matrices with embedded enzymes (urease) or organic polymers using the sol-gel method are also discussed.
