Thermally Switchable Chitosan-Polycarbamate Cross-linked Epoxy Resin Composites with Enhanced Mechanical Strength and UV-A Shielding

Industrial & Engineering Chemistry Research, Год журнала: 2025, Номер unknown

Опубликована: Март 24, 2025

The growing demand for sustainable and high-performance materials has driven the need eco-friendly alternatives in coatings polymer industries. This study introduces a novel approach to enhancing epoxy using chitosan-based polycarbamate derivatives synthesized via nonisocyanate route, offering safer more pathway generating isocyanates. successful formation of isocyanate from was confirmed by experimental techniques such as CO2 evolution, TGA, DSC, along with theoretical validation Dmol3 transition state analysis. generated improved mechanical, chemical, thermal properties made diglycidyl ether bisphenol A (DGEBA) triethylenetetramine (TETA). Cure time analysis showed that incorporating chitosan-blocked significantly increased cross-linking density, resulting than twice tensile strength modified films (51 MPa) compared unmodified ones (24 MPa). Additionally, exhibited better flexibility, stiffness, chemical resistance, UV stability, lower surface wettability. system presents scalable, cost-effective solution industries seeking greener protective coatings, adhesives, advanced applications. These findings pave way industrial adoption biobased, materials, promoting environmental sustainability without compromising functionality.

Chitin, Chitosan and Its Derivatives: Antimicrobials and/or Mitigators of Water

Macromol—A Journal of Macromolecular Research, Год журнала: 2025, Номер 5(2), С. 15 - 15

Опубликована: Апрель 8, 2025

Antimicrobial resistance (AMR) is a major global health problem, exacerbated by the excessive and inappropriate use of antibiotics in human medicine, animal care agriculture. Therefore, new strategies compounds are needed to overcome this issue. In view, it may be appropriate reconsider existing biomaterials alleviate antibiotic overuse. Chitin, naturally abundant amino mucopolysaccharide, poly-β-1, 4-N-acetylglucosamine (GlcNAc). It white, hard, inelastic, nitrogenous polysaccharide source surface pollution coastal areas. Chitosan derives from partial N-deacetylation chitin originates shells crustaceans fungi cell walls. nontoxic natural antimicrobial polymer approved GRAS (Generally Recognized as Safe United States Food Drug Administration). Chitin chitosan, non-toxic biopolymers, useful for wastewater treatment remove pollutants, such pharmaceuticals, heavy metals dyes. The described features make these biopolymers intriguing investigated their application antibacterials.

Melt-Processed Polybutylene-Succinate Biocomposites with Chitosan: Development and Characterization of Rheological, Thermal, Mechanical and Antimicrobial Properties

Polymers, Год журнала: 2024, Номер 16(19), С. 2808 - 2808

Опубликована: Окт. 3, 2024

The current research is devoted to the development and characterization of green antimicrobial polymer biocomposites for food packaging applications. were developed by melt compounding on basis two different succinate matrices with varying chain stiffness—polybutylene (PBS) or its copolymer 20 mol.% polybutylene adipate (PBSA). Fungi chitosan oligosaccharide (C98) crustacean (C95) used as additives. rheological properties determined clear out most suitable temperature processing. In addition, mechanical, thermal, barrier determined. results investigation revealed that PBSA composites 7 wt% 10 C98 additive more films because their higher ultimate elongation values, better damping well superior anti-microbial behavior. However, due lower thermal stability PBSA, processing temperatures desirably should not exceed 120 °C. Additionally, considering decreased moisture vapor properties, it recommended perform further modifications PBSA-C98 through an addition a nanoclay excellent stability.

Evaluating Nudaurelia dione (Saturniidae), an Edible Insect, for Sustainable Nutrition: Composition, Benefits, and Antinutritional Insights

Journal of Food Biochemistry, Год журнала: 2024, Номер 2024(1)

Опубликована: Янв. 1, 2024

Increasingly, insects are heralded as a sustainable and efficacious solution to global challenges of malnutrition protein scarcity. The Food Agriculture Organization (FAO) advocates for the use substitute conventional animal‐based proteins, in response escalating pressures on natural resources environment. This study focuses Nudaurelia dione , exploring its nutritional antinutritional profiles through rigorous laboratory analyses employing standardized methodologies. Our findings establish that N. is potent source macronutrients, providing significant quantities lipids, carbohydrates, with calculated energy content 413.64 ± 13.32 kcal per 100 g dry matter (DM). lipid fraction particularly rich essential fatty acids, including α ‐linolenic linoleic acids. Additionally, insect species contains high levels minerals such calcium, magnesium, sodium, potassium. Despite these benefits, presence considerable amounts phytates (2059.96 5.12 mg DM) poses potential health risks. Therefore, it imperative develop apply appropriate processing methods reduce factors effectively.
