Biodegradation of Ultrafine Fibrous Materials Based on Blends of Poly(hydroxybutyrate) and Polylactide
Tóm tắt
Comparative studies of ozone and oxygen effects, hydrolytic destruction, and biodegradation of nonwoven fibrous and film materials based on blends of natural polymers (poly(hydroxybutyrate) and polylactide) have been carried out. Fibers were obtained from a solution in chloroform via the electrospinning method. The films were obtained by electrospinning from solution in chloroform. The structure of materials has been investigated via electron and optical microscopy, differential scanning calorimetry, electron paramagnetic resonance spectroscopy. It has been shown that the polylactide-enriched materials have greater resistance to oxidation and low resistance to hydrolysis and UV radiation compared to poly(hydroxybutyrate).
