Structural and thermomechanical investigation of lyotropic liquid crystal phases doped with monodisperse microparticles
Appl. Rheol. 24:1 (2014) 14147 (7 pages) ►
We present a study of the structural and thermomechanical properties of lyotropic phase in the quasi ternary system made of Cetylpyridinium chloride (CPCl)/hexanol/salt water (0.9% by mass) with and without cobalt microparticles. Phase transition temperatures of the structural sequence isotropic L1/nematic calamitic Nc,/hexagonal H have been determined by differential scanning microcalorimetry. Temperature induced developable domains in hexagonal phase H and disclinations in calamitic nematic phase Nc were observed in crossed polar optical microscopy in confined geometry. A rheological study of calamitic nematic phase Nc highlighted structuring effect of cobalt microparticles from a concentration of 2% to be demonstrated by an increase in viscosity and viscoelastic moduli. This could be explained by a stabilization of disclinations.► Cite this publication as follows:
