The Corset Effect, Field-Cycling NMR Relaxometry, Transverse NMR Relaxation, Field-Gradient NMR Diffusometry, and Incoherent Neutron Scattering
摘要：
束腹效应是一种实验上建立的动态约束现象，首先通过场循环NMR弛豫法和横向NMR弛豫法在聚合物熔体中观察到，聚合物熔体的孔隙尺寸从几纳米到0.06微米甚至更大。所采用的技术是特别敏感的聚合物链段的旋转波动。它将被证明，中子散射和其他方法探测平移波动是不适合这种现象的检测。
英文摘要：
The corset effect is an experimentally established dynamic confinement phenomenon first observed by field-cycling NMR relaxometry and transverse NMR relaxation in polymer melts in pores with dimensions ranging from a few nanometers up to 0.06 micrometers or even more. The techniques employed are specifically sensitive to rotational fluctuations of polymer segments. It will be shown that neutron scattering and other methods probing translational fluctuations are not suitable for the detection of this phenomenon.
