摘要: Using electrospinning technique, well-aligned poly(azo-ether-imide) (PAEI) nano-fibers and PAEI/multi- walled carbon nanotube (MWCNT) were developed in this effort. Afterwards, polystyrene-b-poly (ethylene-ran-butylene)-b-polystyrene (SEBS) polyimide-based nano-fiber films casted. The as-prepared electrospun nanofibers acted as homogeneous reinforcement to enhance the tensile strength heat resistance of films. Compared with neat SEBS, reinforced PAEI PAEI/MWCNT remarkably increased by >181%. significant enhancement overall mechanical properties SEBS was credited fine compatibility between matrix well superior orientation matrix. alignment also studied using SEM micrographs. Moreover, thermal stability found be having 10% gravimetric loss range 591-602℃ glass transition temperature 238-255℃ relative polymer nano-fiber-based system.
