Abstract: (950 Views)
In this paper, the patterning process of Electrospun piezoelectric PVDF nanofibers is studied. For this purpose, first nanofibers are made using electrospinning method with optimal conditions. Then the resulting nanofibers scaffold was patterned using the femtosecond pulses of Ti:Sapphire laser and micrometer channels and patterns were created on it. The structure and morphology of the nanofibers and the created patterns are investigated by scanning electron microscopy (SEM). The results show that the patterned nanofibers scaffold using femtosecond laser pulses can be used as a neural tissue-engineering scaffold.
Keywords: Femtosecond pulses, nanofibers scaffold, patterning, piezoelectric PVDF polymer, Ti:Sapphire laser
