Abstract:
Liquid crystal compositions comprising a crude liquid crystal sample containing ions and polyamide particles are disclosed. Upon separation of the polyamide particles from the crude liquid crystal sample, a purified liquid crystal sample is produced, which shows a 1-2× reduction in ion concentration. Methods for carrying out purification processes are also disclosed.
