This invention relates to a method for electric field orientation of liquid crystal polymers and oriented materials of liquid crystal polymers obtained by the method. This electric field orientation method comprises applying a pulsating electric field which is predominantly unidirectional and whose magnitude is varying periodically or non-periodically to a liquid crystal polymer capable of forming an optically anisotropic melt phase. The oriented material of liquid crystal polymer thus obtained has been unidirectionally oriented and polarized. This oriented, polarized material of liquid crystal polymer can be utilized as a piezoelectric material, pyroelectric material, electret material, non-linear optical element or the like.
A method for electric field orientation of liquid crystal polymers which comprises subjecting a liquid crystal polymer capable of forming an optically anisotropic melt phase to a pulsating electric field which is predominantly unidirectional and which has a frequency of not less than 10 Hz so that the molecules of said liquid crystal polymer are uniformly oriented and polarized.
