Shape Templating Effects Among Growing Anisotropic Particles

ORAL

Abstract

This study illustrates an orientational templating mechanism by which anisotropic grain shape coupled with sporadic nucleation generates orientational correlations. A modeling and simulation study indicated that despite the randomness of nucleation and growth, such particles tend to align laterally to each other which leads to an azimuthal inter-grain orientational correlation among such particles. The simulation results agree with crystallization studies on small molecule crystals as well as experimental observation of inter-lamellar correlations in block copolymers.
