Mesure de la conductivité thermique et détermination de l'orientation des molécules a l'interface nématique isotrope de MBBA

Abstract

2014 We have investigated the thermal properties of a nematic liquid crystal (MBBA). We have determined the temperature dependence of the anisotropic heat conductivity. We have also studied the interface between the nematic and isotropic phases. The boundary condition is oblique (conical condition). Several applications are discussed (thermal hysteresis, disclination lines in the plane of the interface, possible heat convection effects). LE JOURNAL DE PHYSIQUE TOME 35, FÉVRIER 1974,
