The thickening mechanism of HEC can primarily be attributed to two main processes hydrophilic interactions and entanglement of polymer chains. Firstly, the hydrophilic hydroxyl groups present in the HEC structure create strong hydrogen bonds with water molecules. This interaction leads to the hydration of the polymer and increases the viscosity of the solution. When sufficient HEC is added to water, the viscosity continues to rise as the polymer chains become more and more stranded in the solvent, resisting flow due to the extensive hydrogen bonding.
