In this paper flexible electrospun mats based on poly(lactic acid) (PLA) blended with 25 wt% of poly(hydroxibutyrate) (PHB) and further plasticized with three different concentration of oligomeric lactic acid (OLA) were developed. The morphological, structural, thermal and mechanical performance of...
