Natural Polymers Used in Edible Food Packaging—History, Function and Application Trends as a Sustainable Alternative to Synthetic Plastic

Polysaccharides, Journal Year: 2021, Volume and Issue: 3(1), P. 32 - 58

Published: Dec. 29, 2021

In this review, a historical perspective, functional and application trends of natural polymers used to the development edible food packaging were presented discussed. Polysaccharides proteins, i.e., alginate; carrageenan; chitosan; starch; pea protein, considered. These are important materials obtained from renewable plant, algae animal sources, as well agroindustrial residues. Historically, some them have been widely by ancient populations for until these replaced petroleum-based plastic after World War II. Nowadays, biobased attracted attention. Their use was boosted especially because environmental pollution caused inappropriate disposal packaging. Biobased welcome design they possess many advantages, such biodegradability, biocompatibility low toxicity. Depending on formulation, certain biopolymer-based may present good barrier properties, antimicrobial antioxidant activities Thus, polysaccharides proteins can be combined form diverse composite films with improved mechanical biological behaviors, making suitable different products.

On the Welding of Vitrimers: Chemistry, Mechanics and Applications

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(36)

Published: May 18, 2023

Abstract Linear chains in thermoplastics make them relatively weak performance but inherently weldable and recyclable. By contrast, thermosets with permanently crosslinked networks possess outstanding mechanical performance, thermal, chemical stability, are unweldable unrecyclable. In the last decade, a kind of thermoplastics‐like termed as vitrimer has been developed extensive applications, which welding vitrimers plays central fundamental role. Herein, we present current state art discuss from broad picture chemistry, physics, mechanics: i) chemistry mechanics vitrimers; ii) applicability assessment methods for iii) design principles implement strategies to iv) effects conditions on strength toughness; v) applications adhesion chemically inert materials. Finally, advantages, challenges, open questions highlighted, future opportunities mechanics, tough welding, artificial intelligence aided programming technology, standard, so discussed. The development would fuse disciplines transformative impact polymer industry.

Alginate-metal cation interactions: Macromolecular approach

Carbohydrate Polymers, Journal Year: 2023, Volume and Issue: 321, P. 121280 - 121280

Published: Aug. 10, 2023

Alginates are a broad family of linear (unbranched) polysaccharides derived from brown seaweeds and some bacteria. Despite having only two monomers, i.e. β-d-mannuronate (M) its C5 epimer α-l-guluronate (G), their blockwise arrangement in oligomannuronate (..MMM..), oligoguluronate (..GGG..), polyalternating (..MGMG..) blocks endows it with rather complex interaction pattern specific counterions salts. Classic polyelectrolyte theories well apply to alginate as polyanion the monovalent non-gelling divalent cations. The use gelling ions, such Ca2+, Ba2+ or Sr2+, provides thermostable homogeneous heterogeneous hydrogels where block composition affects both macroscopic microscopic properties. mechanism gelation is still explained terms original egg-box model, although over years novel insights have been proposed. In this review we summarize several decades research related structure-functionships alginates presence cations present applications field self-assembling nanoparticles radionuclides.
