Abstract

Bathochromic shift in terms of temperature was noticed in p-(p'-ethoxy benzylidene)-p-cyano aniline (EBCA) on dispersion of nano ZnO particles and all the computed optical properties like birefringence, absorption coefficient, phase retardation, order parameter, etc. through statistical method of textures exhibit hypsochromic shift in their values. These changes were assigned to perturbation of lattice arrangement of host EBCA mesogen due to nano ZnO particles. The present studies also confirm the controversial behaviour of material when brought to nano size. Techniques involved in the current investigation are polarizing optical microscopy, differential scanning caloriemetry, powder X-ray diffraction spectroscopy and statistical analysis using MatLab. Detailed analyses of observed changes in nano dispersed p-(p'-ethoxy benzylidene)-p-cyano aniline (EBCA) were reported.
