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)。

Abstract

Amine framework porous polymer (AFPP) were derived from melamine (MA) and terephthalic-aldehyde (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—CR₁R₂—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 389.82m²/g,and the structure of AFPP-2 exhibited “micro-meso-macroporous”.Hydrogen uptake capacity of AFPP-2 was 9.02wt% under the condition of 298K and 4.72MPa.
