摘要: An explanation of the puzzling temperature dependent intensity behavior observed in T1ρ data for isotropic FEP polymer is put forth a simple model invoking spin diffusion between crystalline and amorphous phases. In order to explain similar from fibers more detailed different morphology proposed which interfacial geometry plays an important role. It appears that morphological history samples factor relaxation behavior.
