Abstract

A mechanism is proposed for the cryostructuring of aqueous solutions of polyvinyl alcohol, that is, for converting the solutions from a fluid state into elastic bodies (cryogels). In addition to the theoretical justification for the mechanism, experimental results of rheological and spectroscopic studies of the resulting cryogels are also presented. An explanation is given for the significant difference between the cryostructuring temperature of an aqueous solution of polyvinyl alcohol and the melting temperature of elastic cryogels formed from it.

期刊介绍： The journal publishes theoretical and applied articles on the chemistry and physics of solid fuels and carbonaceous materials. It addresses the composition, structure, and properties of solid fuels. The aim of the published articles is to demonstrate how novel discoveries, developments, and theories may be used in improved analysis and design of new types of fuels, chemicals, and by-products. The journal is particularly concerned with technological aspects of various chemical conversion processes and includes papers related to geochemistry, petrology and systematization of fossil fuels, their beneficiation and preparation for processing, the processes themselves, and the ultimate recovery of the liquid or gaseous end products.
