Nonequilibrium Disclinations in the Carbonaceous Mesophase.
Abstract
The behavior of carbonaceous mesophase in the liquid crystalline state has been observed directly by polarized light on the free surface of a petroleum pitch during pyrolysis. The present work focuses attention on the reactions between various disclinations, and primarily on the spontaneous generation of new disclinations from compressed folds in the mesophase layers. Specimens quenched from critical stages in such reactions reveal that structures of freshly formed disclinations can be distorted appreciably from the equilibrium structures of relaxed disclinations.
