Abstract Reversible and recyclable thermosets have garnered increasing attention for their smart functionality sustainability. However, they still face challenges in balancing comprehensive performance dynamic features. Herein, silicon (Si)─oxygen (O) imidazole units covalent bonds are coupled to generate a new class of bio‐polyimines (Bio‐Si‐PABZs), endow them with high excellent reprocessing capability acid‐degradability. By tailoring the molar content diamines, this Bio‐Si‐PABZs displayed both markedly glass transition temperature (162 °C) char yield at 800 °C an oxygen atmosphere (73.1%). These favorable properties outperformed various previously reported polyimines competed effectively commercial fossil‐based polycarbonate. Moreover, scratch (≈10 µ m) on surface samples can be self‐healing within only 2 min, effective “ Bird Nest ”‐to‐“ Torch ” recycling also achieved through free amines solution. Most importantly, bio‐based siloxane adhesive derived from intermediate Bio‐Si‐PABZ‐1 by acidic degradation demonstrated broad robust adhesion substrates, values reaching up ≈3.5 MPa. For first time, study lays scientific groundwork designing polyimine Si─O units, as well converting plastic wastes into thermal‐reversibility renewable adhesives.

The escalating concern about plastic pollution has intensified research efforts in developing degradable bioplastics. However, the fabrication processes of all-natural bioplastics are fraught with tremendous challenges, notably use toxic chemicals and generation hazardous waste. Herein, we report an environmentally friendly method for synthesizing a sustainable konjac glucomannan (KGM) bioplastic. intermolecular interactions KGM chains were reconstructed by substituting original H-bonds dynamic covalent bonds, which formed via Schiff base reaction at oil–water interface. resulting thermo-processable bioplastic exhibited multiple advantages, such as low glass-transition temperature (Tg), rehealability, reprocessability, satisfactory tensile strain, excellent resistance to water other chemicals. Significantly, only was used medium throughout entire preparation, avoided consumption organic solvents production This work provides eco-friendly approach craft viable alternatives traditional plastics.

Coassembly of hybrid microscale biomatter for robust, water-processable, and sustainable bioplastics

Science Advances, Год журнала: 2025, Номер 11(14)

Опубликована: Апрель 2, 2025

Unlike conventional methods that typically involve extracting biopolymers/monomers from biomass using lots of hazardous chemicals and high energy, the direct utilization biological matter (biomatter) without extraction offers a more sustainable alternative for bioplastic production. However, it often suffers insufficient mechanical performances or limited processabilities. Herein, we proposed hybrid microscale biomatter coassembly strategy leverages interactions between inherent microarchitectures waste cotton fiber pollen particles. With minimal preprocessing, they form castable slurry can spontaneously organize into dense fiber-laminate network, exhibiting properties (52.22 megapascals 2.24 gigapascals) toxic organic heavy machinery. The resulting features controlled hydration-induced microstructural disassembly/reassembly, enabling water-based processability complex, dynamic architectural systems. In addition, demonstrates good biodegradability, closed-loop recyclability, satisfactory environmental benefits, outperforming most common plastics. This study provides an instant nature-derived paradigm bioplastics’ production, processing, recycling, offering promising solution facilitating eco-friendly advanced applications.

All-Natural Chitosan-Based Polyimine Vitrimer with Multiple Advantages: A Novel Strategy to Solve Nondegradable Plastic Waste Pollution

Опубликована: Янв. 1, 2023

The increasing amount of nondegradable petroleum-based plastic waste releases chemical hazards, posing a significant threat to the environment and human health. Chitosan, derived from marine wastes, is an attractive feedstock for preparation replacement due its renewable degradable nature. However, in most cases, complex modifications chitosan or hybridization with chemicals fossil resources are required. Herein, we present high-performance chitosan-based polyimine vitrimer (CS-PI) through mild catalyst-free Schiff base reaction between vanillin. CS-PI were formed by integrating dynamic imine bonds into polymer networks, resulting superior thermo-processability mechanical performances. tensile strength Young’s modulus films reached 38.72 MPa 3.22 GPa, respectively, which was significantly higher than that both commercial plastics bioplastics. Additionally, exhibited good light transmittance, self-healing ability, reprocess capacity, water resistance, durability various organic solvents. Moreover, could be completely degraded under acidic natural conditions, enabling sustainable circulation. Therefore, this work offers new design strategy developing all-natural environmentally friendly polymers as replacements plastics, thus reducing accumulation waste.
