Melnyk I. Synthesis and research of polyorganosiloxanes with a bi- and trifunctional superficial layer

The object is the study of influence of synthesis conditions on the base physical and chemical and structural-adsorption characteristics of hybrid organic-inorganic sorptional materials with a bi- and trifunctional surface layers; the purpose is development (with use sol-gel and template methods of synthesis) of simple and effective ways of reception polysiloxane xerogels and mesoporous silica with bi-and trifunctional surface layers, an establishment of their composition and a structure, studying sorption properties and research factors of influence on their structural-adsorption characteristics; methods - DTA, XRD, TEM, SEM, IR- and Ramman spectroscopy, (solid-state) NMR spectroscopy on nucleus 13С that 29Si, adsorption method; novelty - the influence ratio of reacting components (organosilane) and the nature of functional groups on structural-sorption characteristics of sorbents with sulfur-containing surface layer is established; results - obtained xerogels and mesoporous silica can be used as selective sorbents of toxic metals; the field is chemistry and physics of a surface.
