Production of hydrophobic surfaces in biodegradable and biocompatible polymers using polymer solution electrospinning

In this work, the electrospinning of polymer solutions was used to produce mats with hydrophobic properties from a series of commercially available biodegradable and biocompatible polymers, such as poly(3-hydroxybutyric acid-co-3-hydroxyvaleric acid), poly(DL-lactide), polycaprolactone, and poly(L-l...

Description
Summary:In this work, the electrospinning of polymer solutions was used to produce mats with hydrophobic properties from a series of commercially available biodegradable and biocompatible polymers, such as poly(3-hydroxybutyric acid-co-3-hydroxyvaleric acid), poly(DL-lactide), polycaprolactone, and poly(L-lactide). According to the results, to obtain hydrophobic properties, bead-like morphologies were the most adequate. For obtaining this type of morphology, the polymer concentration of the electrospun solution had to be sufficiently low, although below a limit concentration it was not possible to obtain hydrophobic surfaces. The results also showed that the crystallinity of the materials may influence the final hydrophobic properties.
