说明

應用

• Bioplastic Films from Moringa Oleifera Gum: This paper discusses the development of scalable and degradable bioplastic films from Moringa oleifera gum mixed with polyvinyl alcohol, intended for sustainable packaging solutions (Ranote et al., 2024).


• High-Density Polyethylene Modification: The modification of high-density polyethylene with a fibrillar-porous structure using biocompatible polyvinyl alcohol is studied to improve its mechanical properties and environmental performance (Yarysheva and Arzhakova, 2024).


• Cellulose Nanofiber Reinforced Polyvinyl Alcohol Hydrogels: This research explores the creation of high-strength, anti-fatigue cellulose nanofiber reinforced polyvinyl alcohol-based ionic conductive hydrogels, targeting applications in flexible strain/pressure sensors and triboelectric nanogenerators (Li et al., 2024).
