چکیده
Deficient cell proliferation on vascular grafts can cause coronary thrombosis and despite all recent innovations in vascular tissue engineering, fabricating novel materials with superior hemocompatibility remains a challenge. In this work, poly (ethylene terephthalate) (PET)/carboxylated multi-walled carbon nanotubes (CMWCNT) nanofibers were prepared via electrospinning. The results showed that the optimum value of CMWCNT content was 1% which in turn the average diameter of nanofibers, electrical conductivity and water contact angle were obtained 188 nm, 4.47×10-9, and 120º, respectively. To assess the hemocompatibility of the PET/CMWCNT1% nanofibers, aspirin (2 wt. % per polymer weight) as an anticoagulant drug was used and outcomes revealed that the blood platelets adhesion spreading was less than that of sample without the drug.
