摘　　要：以三聚氰胺和对苯二甲醛为原料,通过溶剂热法制备出含胺基骨架多孔聚合物(AFPP),利用傅里叶变换红外光谱仪、扫描电子显微镜、微孔分析仪和储氢分析仪等现代分析手段对其结构和性能进行表征。结果表明:AFPP的主体骨架链接结构为缩醛胺结构(—N—CR1R2—N—);当三聚氰胺和对苯二甲醛摩尔比为2∶3时,合成的AFPP-2比表面积为389.82m2/g,且具有微孔-中孔-大孔的层次结构;储氢性能分析显示AFPP-2在298K、4.72MPa条件下,氢气吸附量达到9.02%(质量分数)。Amine framework porous polymer(AFPP)were derived from melamine(MA)and terephthalicaldehyde(TA)by solvothermal reaction.And the structure characterized by Fourier transform infrared spectroscopy(FT-IR),scanning electron microscope(SEM),microporous analyzer,hydrogen storage tester and other analytical methods.The results showed that AFPPs obtained from reaction of melamine and terephthalic-aldehyde to form aldehyde amine(-N-CR1 R2-N-)frameworks structure by solvothermal method.When the monomer molar ratio was 2∶3(amine∶terephthalic-aldehyde)named AFPP-2,BET specific surface area was 389.82 m^2/g,and the structure of AFPP-2 exhibited "micro-meso-macroporous".Hydrogen uptake capacity of AFPP-2 was 9.02 wt% under the condition of 298 Kand 4.72 MPa.
