Biocomposite PBAT/lignin blown films with enhanced photo-stability

Lignin-containing biodegradable UV-blocking films: a review

“…The resulting PBAT/lignin film exhibited an improvement in the elastic modulus in contrast to pure PBAT membranes, without compromising the elongation at break. 135 Moreover, some additional modifiers were also added to the PBAT–lignin composite film to maximize its performance. Starch/PBAT films with remarkable resistance to ultraviolet aging and excellent mechanical properties were successfully prepared by incorporating lignin.…”

Lignin Modification for Enhanced Performance of Polymer Composites

“…At a lignin loading of 10%, the films demonstrated outstanding UV-barrier properties and provided complete protection from UV irradiation between 280 and 400 nm. Botta et al 228 demonstrated the suitability of lignin for the production of biocomposites PBAT-blown films improved rigidity. Lignin also contributes aids in the production of biodegradable films with optimal productivity of photo-oxidation resistance while choosing the correct filler concentration.…”

Fabrication of biodegradable hollow microsphere composites made of polybutylene adipate co-terephthalate/polyvinylpyrrolidone for drug delivery and sustained release

“…The method used to prepare microspheres with synthetic polymer materials is not only easier to control, but the obtained microspheres possess excellent mechanical properties and more controllable drug release compared with those prepared with natural polymer materials [ [34] , [35] , [36] ]. Microspheres prepared from PLGA, polycaprolactone [ 37 , 38 ] (PCL), polylactic acid [ [39] , [40] , [41] ] (PLA), and other synthetic polymers have been reported many times, while those prepared from polybutylene adipate [ [42] , [43] , [44] ] (PBAT) have not yet been reported. PBAT is a synthetic polymer with good biocompatibility and biodegradability, and the products after complete degradation are water and carbon dioxide.…”
