P(MEO_2MA-co-OEGMA)共聚物的表面附着结构是具有热响应性的聚乙二醇类类似物,在生物技术和医学方面具有潜在的应用前景。在这方面,由这些共聚物制成的聚合物刷的结构和动力学引起了人们的极大兴趣。用掠入射条件下的中子自旋回波谱(GINSES)研究了高度为250 nm的p(MEO_2MA-co-OEGMA)电刷的近表面动力学。研究了中子在两个穿透深度下的刷子动力学。研究发现,距离约束表面的距离对集体扩散有一定的影响。首次证明了用中子自旋回波谱研究掠入射下单平面液/固界面大分子热涨落的可行性。
Surface-attached architectures of p(MEO2MA-co-OEGMA) copolymers are thermoresponsive PEG analogues with potential applications in biotechnology and medicine. In this respect, structure and dynamics of polymer brushes made of these copolymers are of great interest. In this work, the near surface dynamics of a p(MEO2MA-co-OEGMA) brush with a height of 250 nm was investigated with neutron spin echo spectroscopy under grazing incidence (GINSES) conditions. The brush dynamics was studied at two penetration depths of the neutrons. An influence of the distance from the confining surface on the collective diffusion was found. For the first time, the experiment demonstrates the feasibility of studying thermal fluctuations of macromolecules at a single planar liquid/solid interface by neutron spin echo spectroscopy under grazing incidence.
