Abstract

In this study, a combination of poly (3-hydroxybutyrate) (PHB), chitosan (Cs), multiwall carbon nanotubes (MWNTs), and different concentrations of Hyaluronic Acid (HA) were electrospun. The results showed that the produced nanofibers are uniform. Incorporation of HA, Cs and MWNTs reduced the water contact angle and made the scaffolds more hydrophilic. The porosity of the scaffolds was in the range of 80-88%. The presence of MWNTs increased the tensile strength of scaffolds and different concentrations of HA had no much diverse effects. In conclusion, the PHB-Cs-MWNTs-HA 10% electrospun scaffold could be a good candidate for cartilage tissue engineering applications.
