摘要

Conductivity of a doubly‐oriented polymer along the arbitrary direction (X, Y, Z) is presented as a function of the principal values of the conductivity σx, σy, σz of the orientation units (’’crystals’’) and a double orientation function of ’’crystals’’. Principal values of the electrical conductivity in doubly‐oriented nylon 12 films were measured and σx, σy, σz of the crystals of nylon 12 were estimated assuming a suitable distribution of crystals in nylon 12 film. It is observed that σx is much larger than σy and σz. The x direction was defined as the direction of the chain of the hydrogen bonds, i.e., the conductivity along the direction of hydrogen bonds is the largest. The average conductivity σ0 (3σ0 = σx+σy +σz ), which should be independent of the results of orientation, decreased as the roll ratio became large. The decrease of σ0 shows the change of the conduction properties of crystals by rolling, and is considered as a result of the change of the microstructure of nylon 12.
