In this research, nanocomposite nanofibrous webs of poly(acrylic acid) (PAA)/multi‐walled carbon nanotubes (MWNTs) were obtained via electrospinning. The effect MWNTs concentration on the morphology and mechanical properties PAA/MWNTs nanofibers was investigated by changing content from 0 to 5 wt%. results showed that average diameter increased with increasing presence led enhancement properties. Also, revealed strength, modulus, elongation at break samples 3.22, 2.70, 4.27 fold, respectively, after adding 3 wt% MWNTs. addition, rotating speed collector orientation PAA its investigated. Scanning electron microscopy (SEM) studies demonstrated degree augmentation drum 25 rps. Moreover, decreased increase speed. Improvement nanofiber resulted in superior is, higher strength modulus aligned layers comparison nonaligned (12.6 26.6 respectively). POLYM.
