Aquatic biodegradation of poly(β-hydroxybutyrate) in polylactic acid and maleic anhydride blended fibers
Journal of Polymer Research(2024)
Abstract
In this study PLA and PHB were melt-blended with/without maleic anhydride (MA) as a compatibilizer and melt-spun into a monofilament. The aquatic biodegradation of PLA/PHB fibers was tracked regarding the PLA and PHB components and the total carbon in the blend. Pure PLA fiber was recalcitrant to aquatic biodegradation in the present conditions, whereas PHB was readily degradable, as expected. The 75/25
