Determination of Material Constants of Antiferroelectric Liquid Crystal Mixture CS4001.

This work outlines a number of experimental techniques that can be used to determine some fundamental material constants in antiferroelectric liquid crystal materials, exemplified by results for the commercial AFLC mixture CS4001. The parameters measured range from the helical pitch of the material to the interlayer interaction coefficients, elastic constants and viscosities. The experimental methods employed include a variety of both optical and dielectric techniques. [ABSTRACT FROM AUTHOR]
