Multilayer film comprising polybutylene adipate terephthalate and cellulose nan...
Melendez-Rodriguez, Beatriz; Prieto, Cristina; Pardo-Figuerez, Maria; Angulo, Inmaculada; Bourbon, Ana I.; Amado, Isabel R.In the present study, a multilayer, high-barrier, thin blown film based on a polybutylene adipate terephthalate (PBAT) blend with polyhydroxyalkanoate (PHA), and composed of four layers including a cellulose nanocrystal (CNC) barrier layer and an electrospun poly(3-hydroxybutyrateco-3-hydroxyvalerate) (PHBV) hot-tack layer, was characterized in terms of the surface roughness, surface tension, migration, mechani...
High-oxygen-barrier multilayer films based on polyhydroxyalkanoates and cellulo...
Melendez-Rodriguez, Beatriz; Torres-Giner, Sergio; Angulo, Inmaculada; Pardo-Figuerez, Maria; Hilliou, L.; Escuin, Jose Manuel; Cabedo, LuisThis study reports on the development and characterization of organic recyclable high-oxygen-barrier multilayer films based on different commercial polyhydroxyalkanoate (PHA) materials, including a blend with commercial poly(butylene adipate-<i>co</i>-terephthalate) (PBAT), which contained an inner layer of cellulose nanocrystals (CNCs) and an electrospun hot-tack adhesive layer of poly(3-hydroxybutyrate-<i>co<...
Characterization of polyhydroxyalkanoate blends incorporating unpurified biosus...
Martínez-Abad, Antonio; Cabedo, Luis; Oliveira, Catarina S. S.; Hilliou, L.; Reis, Maria; Lagarón, José MaríaPoly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) produced by mixed bacterial cultures derived from a cheese whey (CW) industrial by-product (unpurified PHBV; u-PHBV) was incorporated into commercial PHBV without previous purification or isolation processes. The presence of certain impurities was evident as investigated by scanning electron microscopy. The crystallinity of the polymer fraction was decreased b...
