DEVELOPMENT OF AN INSTRUMENT TO STUDY NANO-RHEOLOGY AND LOCAL DYNAMICS AT POLYMER SURFACES

由于表面与不同的相接触，聚合物表面的聚集结构和物理性质与体中的聚集结构和物理性质有很大的不同。在这项研究中，设计了一个研究聚合物表面纳米流变性和局部动力学的仪器。结果表明，表面的热分子运动比体中的热分子运动更活跃。并阐明了这种活化分子在表面迁移的表现机制。

Aggregation structure and physical properties at polymer surfaces are quite different from those in the bulk because surfaces contact with different phases. In this study, an instrument to study nano-rheology and local dynamics at polymer surfaces was designed. As a result, it was revealed that thermal molecular motion at the surface was much activated in comparison with that in the bulk. And, the manifestation mechanism of such an activated molecular mobility at the surface was elucidated.
