摘要:

We demonstrate that an ion beam analysis method that detects the energies of forward recoiling deuterons can be used to measure concentration profiles and tracer diffusion coefficientsD* of a deuterated polymer (d‐polystyrene) diffusing into its hydrogenated analog. TheD*’s decrease asM−2as predicted by the reptation theory of polymer diffusion and agree in magnitude with both the theory and marker displacement measurements ofD* in the same system.
