摘要
应用溶液缩聚法,分别合成了4种不同结构(主链未含杂环和含有杂环)的长链共轭聚席夫碱;产物通过元素分析仪、核磁共振仪、紫外-可见光谱仪和红外光谱仪进行结构表征;分别测量了聚席夫碱的室温电导率和8~14?m红外发射率。结果表明芳香杂环改性的长链共轭聚席夫碱具有较高的室温电导率和较低的红外发射率。
In this paper, different structures of long-chain conjugated polymer Schiff bases （with heterocyclic aromatic or not） were synthesized via solution polycondensafion. The synthetic products were characterized by UV and IR respectively. Beyond that, their electrical conductivity and infrared emissivity in 8-14 μm were measured. Results show that long chain conjugated structure Schiff bases modified with heterocyclic aromatic have higher electrical conductivity and lower infrared emissivity, that is to say, they have the better infrared stealth performance.
