Abstract Questions and potential misperceptions have arisen about the contribution of liquid detergent capsules to environmental microplastics issue. The film these detergents is highly water soluble, also in cold water, as it must fully dissolve during every type washing process. Water-soluble grades polyvinyl alcohol, most commonly used capsule material, are recognised be biodegradable. In cu...

Abstract This study evaluates the possibility of using polyvinyl alcohol (PVAL) composites as phantom material to simulate different densities breast tissue for mammography based on their elastic properties. Three categories PVAL gels were prepared by freezing and thawing 10 % water (PVAL), ethanol (PVAL/E) a blend with graphite powder (PVAL/G) solutions mimic various densities. Young’s modulus...

Bio-films have been produced that attract attention with their functional behavior among conventional food packaging materials of bio-based polymer blends. The physical and morphological properties copolymeric biofilms extensively investigated. Biodegradable copolymer films were by in situ polymerization technique prepared as solution casting. strong water absorbency polyvinyl alcohol the antim...

BACKGROUND: Biotechnology applications of magnetic gels include biosensors, targeted drug delivery, artificial muscles and magnetic buckles. These gels are produced by incorporating magnetic materials in the polymer composites. METHODS: A biocompatible magnetic gel film has been synthesized using polyvinyl alcohol. The magnetic gel was dried to generate a biocompatible magnetic film. Nanosized ...

Polyvinyl alcohol (PVA) and pectin blends were used to entrap α-amylase (Termamyl) using glutaraldehyde as a cross-linker. The effect of glutaraldehyde concentration (0.25, 0.5, 0.75, 1.0, and 1.25%) on the activity of the immobilized enzyme and rate of enzyme released was tested during a 24 h period. Characteristics of the material, such as scanning electron microscopy (SEM), tensile strength ...
