Theory of light scattering from oriented and fiber structures

Abstract

Abstract Recent progress in the theory of scattering by spherulites of crystalline polymers is reviewed. The consequences of arbitrary optic axis orientation, periodicity of optic axis orientation and of spherulite deformation are described. The transmission of light by a film of a crystalline polymer having spherulitie or lower degrees of order of crystalline orientation is discussed. A theory of the scattering of light from such a film having nonrandom correlation in crystalline orientation is developed. The dependence of the scattered intensity on the polarization directions of the incident and scattered light is shown to depend upon a parameter which characterizes the nonrandomness.
