Abstract
Effects of polymer concentration and temperature on the developmental conditions and structure of wavy texture were experimentally studied using aqueous solutions of hydroxypropylcellulose (HPC). A variety of phases were observed at various HPC concentrations and temperatures: liquid crystalline (LC) phase, isotropic (I) phase and coexisting phase (LC+I). The wavy texture was occurred in LC phase and coexisting one with higher orientation order. The phase state affects the apparent shear strain at the onset of wavy texture, especially at low shear rates.
