MeSH headings : Acetamides / chemistry; Cellulose / analogs & derivatives; Cellulose / chemistry; Elasticity; Gels / chemistry; Hydrogen Bonding; Rheology; Solvents / chemistry; Viscosity; Water / chemistry
topics (OpenAlex): Surfactants and Colloidal Systems; Material Dynamics and Properties; Rheology and Fluid Dynamics Studies
TL;DR: The changes in dynamic rheological behavior of the system during gelation correlate well with the combined solubility parameter (delta) and, in particular, the Hansen hydrogen-bonding solubilities parameter index ( delta(h)) of the solvent system, suggesting hydrogen- bonding interactions may be the major route initiating the sol-gel process.
