摘要: Composite hydrogels based on polyacrylamide immobilized nanoparticles of commercial (P25 brand) titanium dioxide and prepared by electric explosion a wire were synthesized. The enthalpy interaction at the polyacrylamide/TiO2 interface was determined microcalorimetry using thermochemical cycle method. Interaction polymer chains with surface TiO2 is energetically unfavorable. absence interactions between hydrogel network favors manifestation UV-induced photocatalytic activity in hydrogel. Immobilization matrix decreases P25 brand nanoparticles, but does not affect bulk evaluated decomposition Methyl Orange dye controlled diffusion rate molecules into depends also aggregation matrix.
