A linear polymerized photopolymer orienting a nematic liquid crystal within nonextensive formalism

摘要

The distribution function of photogenerated cross-links in thin films of poly(vinyl cinnamate) or poly(vinyl 4-methoxy-cinnamate) is investigated within nonextensive statistics, in terms of the irradiation time of these films with linearly polarized UV light. The scalar order parameter is obtained from the generalized distribution function, and is compared to the measured birefringence for some values of the entropic index q. The exposure time dependence of the nematogen scalar order parameter is plotted, and the effect of the nonextensive formalism on its exposure time dependence is presented.
