Studies Of Polymer/Ceramic Solid Electrolyte Interphase And Thermo-/Light-responsive Hyperbranched Macromolecule By Nuclear Magnetic Resonance

In this work,the structure ancd polymer motility of the polymer-cerarmic interphase and the thermo-responsive and light-responsive properties of a thermos-and light-responsive hyperbranched polymer are studied.The main results include:1.It is found that the polymer consisted in the polymer-ceramic complex is mainly in amorphous state according to the results of SEM,XRD and ⁷Li single pulse NMR experiments.The interphase ⁷Li signals are studied by ¹H-⁷Li CP MAS experiment.The differences on motility and temperature dependence of polymer on the interphase are discovered by ¹H-⁷Li WISE experiments.2.The signal assignment of azobenzene's 1H spectrum is conducted through ¹H single pulse and ¹H-¹H COSY experments.Meanwhile,the photosensitive properties of this molecule are studied.The signal assignment of HPEI-IBAm-PABA complex ¹H spectrum is accomplished by ¹H,¹³C,¹H-¹H COSY,¹H-¹³C HSQC experments.The thermo-responsive properties of the polymer HPEI-IBAm-PABA before and after the UV light are studied by heat up ¹H spectra.The influence of photosensitive groups on the thermo-responsive properties of the polymer is studied by ¹H-¹H NOESY experiments on different temperatures and light conditions.
