利用二阶段相分离控制方法制备不同孔径的三维骨架聚合物及配位聚合物材料.在第一阶段的反应诱导相分离中,通过加入十二烷基苯磺酸作为相分离抑制剂,控制了环氧树脂在聚乙二醇介质中固化反应的相分离速率和程度;在第二阶段,将处于亚稳状态的聚合物用ZnSO4或CdSO4水溶液处理,在配合作用的推动下发生二次相分离,并稳定三维骨架结构,最终实现了在1~2μm范围内调节孔径大小.研究了三维连续孔道在充满二乙烯基苯高折射液体后的滤光特性,通过引入金属离子改变固体材料折射率的方法,验证了光在高折射液相中的全反射效应,并从定性角度建立三维骨架材料的孔径及分布与透射光波长范围之间的关系,对新光学现象给出了初步解释.
A two-phase phase separation method was used to prepare three-dimensional framework polymers with different pore sizes and coordination polymer materials.In the first-stage reaction-induced phase separation, dodecylbenzenesulfonic acid was added as a phase separation inhibitor to control In the second stage, the polymer in the metastable state is treated with ZnSO4 or CdSO4 aqueous solution, and secondary phase separation occurs due to the cooperation of the epoxy resin in the polyethylene glycol medium. , And stabilize the three-dimensional framework structure, and ultimately to achieve the pore size in the range of 1 ~ 2μm.The filter properties of three-dimensional continuous channels after filled with high refractive liquid of divinylbenzene were studied by introducing metal ions to change the refractive index of solid materials Method, the total reflection effect of light in the high refractive liquid phase is verified, and the relationship between the aperture and the distribution of the three-dimensional framework material and the wavelength range of the transmitted light is established from a qualitative perspective, and a preliminary explanation is given for the new optical phenomenon.
