Preparation of Sustainable Composite Materials from Bio‐Based Domestic and Industrial Waste: Progress, Problems, and Prospects‐ A Review

Advanced Sustainable Systems, Год журнала: 2024, Номер 8(8)

Опубликована: Март 13, 2024

Abstract Bio‐based waste from households and industries is a big problem for the world, however, turning it into valuable composite materials can offer promising approach to deal with it. It involves conversion of different bio‐based sources such as cellulose farming forestry leftovers, chitin seafood mushrooms, keratin hair, nails, feathers natural fibers. These fibers are then effectively mixed other create having unique properties, high strength stiffness, good thermal electrical conductivity, better barrier properties. Developing these not just environment because reduces landfill reliance on non‐renewable resources, but also make economic sense producers. In this review, basic compounds development them explored discussed in detail. Furthermore, their chemical mechanical properties summarized. final section, brief overview challenges future research needed fast‐evolving field given.

Development and Perspectives of Biobased Thermal Conductive Polymer Composites

ACS Applied Polymer Materials, Год журнала: 2024, Номер 6(21), С. 12914 - 12940

Опубликована: Окт. 23, 2024

With advancements in science and technology market diversification needs, the development of electronic components has focused on miniaturization high integration. At same time, heat generated by these increases rapidly, excessive accumulation affects performance service life equipment; therefore, thermal conductivity materials become an effective way to solve this problem. Over years, polymer-based thermally conductive have attracted much attention because their excellent insulating properties, chemical resistance, easy processing performance. However, polymers commonly used are mostly highly polluting energy-consuming petroleum-based whose large-scale production seriously affected resources environment. As a green, low-carbon, environmentally friendly, resource-efficient alternative material, biobased expected be potential solution for management. So far, reported composites is far from expectation. This review holistically scopes current advances field, focusing preparation process, modification, application prospects composites. Finally, we discuss problems look forward challenges opportunities, which provide ideas research generation

Access to Functionalized Polycarbonates Derived from Fatty Acid Esters via Catalytic ROCOP and Their Potential in Gel Formulations

Macromolecules, Год журнала: 2024, Номер 57(8), С. 3816 - 3823

Опубликована: Апрель 10, 2024

Fatty acid epoxides and carbon dioxide have been used as monomers to create functional polycarbonate macromolecules using catalytic ring-opening copolymerizations, providing molecular weights of up 18.5 kg/mol under controlled conditions. The functionality in these polycarbonates can be via either the pendent ester groups or additional (functional) epoxy monomers, thereby creating terpolymeric compositions with cross-linkable polarity-changing fragments. Potential depolymerization upcycling atoms were investigated, allowing repurposing initial macromolecule into a bifunctional diurethane-diester monomer good yield. prospect bioderived additives biogel formulations was evaluated, showing it improve mechanical adsorption properties castor oil-based polyurethane gels.

Covalent Adaptable Networks Containing Nitrogen-Coordinated Boronic Ester and Imine Bonds

ACS Applied Polymer Materials, Год журнала: 2024, Номер 6(15), С. 9008 - 9016

Опубликована: Июль 31, 2024

Covalent adaptable networks (CANs) are supposed to address the reprocessing and recycling issues of epoxy resins via their reversible cross-linking structures. However, development CANs simultaneously exhibiting high mechanical strength fast-reprocessing ability is still a huge challenge. Herein, with fabricated by modifying linear polymers nitrogen-coordinated boronic ester imine bonds. Owing densities rigid network structures, obtained show breaking ∼76.0 MPa, yield stress ∼81.5 Young's modulus ∼1.67 GPa, respectively. Because fast exchange reaction bonds, as-prepared can be easily processed into desirable shapes within only 1 min at 150 °C under pressure 10 MPa. Moreover, owing this unique feature, quickly reprocessed least three times without losing original properties. Finally, prepared exhibit shape fixed ratio recovery more than ∼90% when used as shape-memory polymers. This study provides feasible solution for constructing mechanically strong thermosets ability, which will contribute next-generation sustainable resins.
