We report on an unusual polymer "yarn ball" microstructure that is created through a template-based synthetic process involving reactive mesogens. We present experimental results of a unique structural transition of the yarn ball when subjected to an electric field, and describe this transition with a modified elastic theory. We model the interactions of the mesogenic thread segments that comprise the yarn ball in terms of mean-field theory by introducing an intersegment potential. © 2000 American Institute of Physics.
