摘　　要：首先通过生物基来源的呋喃二甲酰氯(FDCl)和3,4-二氨基二苯醚(ODA)低温溶液缩聚制备了含呋喃环的芳香聚酰胺树脂溶液(f-resin),采用干喷湿纺得到含呋喃环的芳香聚酰胺纤维(f-fiber)。采用扫描电镜和X射线衍射对f-fiber的表面形貌与聚集态结构进行了分析。结果表明,f-resin的可纺性良好,所得f-fiber粗细均匀,表面光滑,结晶度可达41%以上。就其力学性能、热稳定性、阻燃性与间位芳纶(m-fiber)进行了对比研究,所得f-fiber力学性能、耐热性与阻燃性能优异,略低于间位芳纶,且其原材料来源于生物质,属于环境友好、可持续发展材料,具有广阔的发展前景。An aromatic polyamide resin solution containing furan ring(f-resin)was prepared by polycondensation of low-temperature solution using bio-based furandiyl chloride and 3,4-diaminodiphenyl ether as raw material and N,N-dimethylacetamide as solvent,and then aromatic polyamide fiber containing furan ring(f-fiber)was obtained by dry-jet wet spinning.The surface morphology and aggregate structure of f-fiber were analyzed by scanning electron microscopy(SEM)and X-ray diffraction(XRD),and the results show that the spinnability of f-resin is good,the thickness of f-fiber is uniform,the surface is smooth,and the crystallinity could reach more than 41%.Its mechanical properties,thermal stability,flame retardancy were studied and compared with meta-aramid(m-fiber),which are excellent and slightly lower than those of m-fiber.Besides,raw materials of f-fiber are bio-based,which are environmentally friendly and have broad development prospects.
