A field of polymer chain segments tightens toward the fiber axis as you raise alignment, while the curve translates orientation into relative axial conductivity through a simple series picture: the fewer interchain hops per unit length, the higher the axial channel climbs — and the radial channel stays pinned near bulk. The animated segments and the curve tell one story: chain order is a major lever alongside chemistry, crystallinity, molecular weight, defects and porosity.
Schematic teaching model: orientation-to-conductivity mapping is an illustrative monotone cubic, not a fitted draw-ratio law; real curves depend on polymer, crystallinity and molecular weight. The animated field and the pinned radial floor carry the physics.
