Biopolymer‐Based Flame Retardants and Flame‐Retardant Materials

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 8, 2025

Abstract Polymeric materials featuring excellent flame retardancy are essential for applications requiring high levels of fire safety, while those based on biopolymers highly favored due to their eco‐friendly nature, sustainable characteristics, and abundant availability. This review first outlines the pyrolysis behaviors biopolymers, with particular emphasis naturally occurring ones derived from non‐food sources such as cellulose, chitin/chitosan, alginate, lignin. Then, strategies chemical modifications flame‐retardant purposes through covalent, ionic, coordination bonds presented compared. The is placed advanced methods introducing biopolymer‐based retardants into polymeric matrices fabricating materials. Finally, challenges sustaining current momentum in utilization further discussed.

Facile Fabrication of Highly Efficient Chitosan-Based Multifunctional Coating for Cotton Fabrics with Excellent Flame-Retardant and Antibacterial Properties

Polymers, Journal Year: 2024, Volume and Issue: 16(10), P. 1409 - 1409

Published: May 16, 2024

Interest in the development of eco-friendly, sustainable, and convenient bio-based coatings to enhance flame retardancy antibacterial properties cotton fabrics is growing. In this work, chitosan was protonated at its amino groups using a method with high atom economy an equimolar amount trimethylene phosphonic acid (ATMP), resulting fabrication single-component chitosan-based multifunctional coating (ATMP-CS), thereby avoiding any additional neutralization or purification steps. Cotton coated various loads ATMP-CS were prepared through padding–drying–curing process. The morphology, thermal stability, mechanical properties, flame-retardant behavior, mechanism these investigated. exhibited excellent film-forming it imparted uniform protective layer onto surfaces fabrics. When load capacity reached 11.5%, achieved limiting oxygen index 29.7% successfully passed VFT test. Moreover, demonstrated rates against Escherichia coli Staphylococcus aureus reaching 95.1% 99.9%, respectively. This work presents straightforward gentle approach fabricating colorless, environmentally friendly, highly efficient fabric that have potential applications promoting use materials.

Sustainable Layer‐by‐Layer Films Using Chitosan Decorated With Anthocyanins and Carboxylated Graphene Oxide for Food Packaging Applications

Journal of Polymer Science, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 4, 2025

ABSTRACT The abuse of traditional plastic food packaging has caused severe safety and environmental pollution, urgently necessitating the development green sustainable biodegradable materials. Chitosan (CS) belongs to an inexpensive readily available biopolymer; however, poor mechanical properties weak resistance UV light water make it unsuitable for industry. In this study, a layer‐by‐layer (LBL) assembly CS decorated with anthocyanins as polycationic electrolyte carboxylated graphene oxide (GO‐COOH) polyanionic is used fabricate bio‐based films aim improving comprehensive CS‐based films. results indicate that LBL extremely enhanced UV‐blocking ability (the average transmittance in UV‐B region drops 1.68%), tensile strength (TS) (53.52 MPa), toughness (71.81%), thermal stability, resistance, hydrophobicity contact angle up 109.5°), antioxidant activities films, attributed hydrogen bonds among CS, anthocyanins, GO‐COOH electrostatic interactions between along anthocyanins. addition, show exceptional advantages storage application fresh‐cut apples. general, study demonstrates novel film can be fabricated by technique packaging.
