This work compares the effect of adding different biopolyester electrospun coatings made of polycaprolactone (PCL), polylactic acid (PLA) and polyhydroxybutyrate (PHB) on oxygen and water vapour barrier properties of a thermoplastic corn starch (TPCS) film. The morphology of the developed multilayer structures was also examined by Scanning Electron Microscopy (SEM). Results showed a positive li...

The chemical synthesis of an aliphatic biopolyester identical to the natural cutin which constitutes the major component of the cuticle of fruits and leaves of higher plants is for the first time achieved and reported. Potential applications of this new material is of great interest because its physical properties, non-toxicity, biodegradability, and availability of raw material.

Biodegradable nanofibers are expected to be promising scaffold materials for biomedical engineering, however, biomedical applications require control of the degradation behavior and tissue response of nanofiber scaffolds in vivo. For this purpose, electrospun nanofibers of poly(hydroxyalkanoate)s (PHAs) and poly(lactide)s (PLAs) were subjected to degradation tests in vitro and in vivo. In this ...

Abstract Biopolyesters, pure and mixed with a compatibilizer, are exposed to UV‐C radiation in the interval 4–32 h. rays act as germicides antibacterial on biomedical materials. The mechanical physical characterization tests have shown how all materials, mixed, undergo photodegradation even if different way. change structural order of polymer, embrittlement, surface wettability water/blood is l...
