Polyacrylonitrile (PAN)/ polyurethan e (PU) blend nanofibers were prepared by electrospinning blend solutions of PAN and PU in N,N dimethylformamidedimethylformamide. The morphology, properties and structure of electrospun PAN/PAN nanofibers were characterized using Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), Thermo gravimetric analyses (TGA), mechanical properties measurement and differential scanning calorimetry (DSC). FT-IR indicated that intermolecular interactions are formed between PAN and PU and the SEM images demonstrated that point-bonded structures in the fiber mats rose with increasing PU composition. Furthermore, the elongation and tensile strength of the PAN/PU blend nanofiber mats were significantly increased compared with PAN due to the point-bonded structures..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
