Abstract
This chapter reviews gas permeation and barrier properties of crystalline and
liquid crystalline polymers from both theoretical mechanism and experimental
measurement. The permeability is closely related to both solubility and diffusivity
in polymers. Various factors such as crystallinity and crystalline-amorphous
morphology play important roles in the solubility and diffusivity, and thus the
permeability of crystalline and liquid crystalline polymers.
