Electric properties of metal-organic lyotropic liquid crystals
The electric properties of pure and dye-doped potassium caproate, which in a 1:1 water solution forms at room temperature ionic lyotropic liquid crystals (ILLC) of smectic A type [1], were investigated. It carried out the comparative analysis of electric properties of the investigated objects with o...
