САЖЕТАК / ABSTRACT:
The use of biodegradable polymers from renewable resources in polymer manufacturing, food packaging and for medical application is becoming a favorable option over petroleum-based plastics. Among all biopolymers, biopolyesters poly(lactic acid) (PLA) and polyhidroxyalkanoates (PHAs) are considered as the most commercially promising bioplastics. PLA is a biopolyester produced by polymerization of D-, L- lactic acids originating through fermentation of simple sugars from agricultural sources (corn, potato, sugar cane, sugar beet, etc.). PHA is a generic designation for biopolyesters produced by controlled microbial fermentation in the presence of an abundant source of sugars or lipids. The focus of this study was to prepare fully biodegradable flexible nanomaterials using PLA and poly(hydroxybutyrate) (PHB) polymer blend solution by means of electrospinning technique. Since PHB possesses low resistance to thermal degradation with melting temperatures close to degradation and narrowing the processing window, the electrospinning technique reduces energy consumption and avoids thermal degradation during processing. A complete morphological, structural and thermal characterization of the developed materials was conducted at the same time.
