Free-standing polyelectrolyte multilayer membranes have been formed by the layer-by-layer technique using a dip-coating apparatus. The polymer-chain mobility has been studied by 1H relaxation in the rotating frame T 1rho NMR with 13C chemical shift resolution. For each of the individual polymers a single relaxation component has been observed for all resolved signals. In the multilayer a significantly different relaxation time T 1rho has been observed with a minor second component. The interaction between the oppositely charged polyelectrolytes influences the molecular mobility.

聚电解质多层中的聚合物链迁移率
使用浸涂设备通过逐层技术已经形成了独立式聚电解质多层膜。通过在13 C化学位移分辨率的旋转框架T 1rho NMR中1 H弛豫研究了聚合物链的迁移率。对于每种单独的聚合物,对于所有分辨的信号都观察到单个弛豫成分。在多层结构中,观察到次要成分的弛豫时间T 1rho明显不同。带相反电荷的聚电解质之间的相互作用影响分子迁移率。
