With the rise of circular economy, self-healing polymers have attracted significant attention for their longer lifespan and greater recyclability compared with traditional thermoplastics thermosetting polymers. However, addressing instability units to develop high-performance materials remains a challenge. Herein, we report series superior polyimine derivatives, biobased polyacylhydrazones (bio-PHys), via aldehyde-hydrazide condensation. The coexistence amide bonds imine bonds, which provide hydrogen bonding dynamics, imparts remarkable mechanical properties (tensile strength 103 MPa, elongation at break 180%) bio-PHys, along notable capabilities under glass transition temperature (Tg). Bio-PHys also exhibits potential scalable production, excellent processability, photoluminescence characteristics. We explored its application in adhesive-free laminated substrates thoroughly investigated aggregation-induced emission acylhydrazone group. Furthermore, utilized bio-PHys create recyclable smart paper anticounterfeiting dynamic information storage. This work presents novel approach developing

Designing Biobased Poly(ethylene-co-isosorbide terephthalate) Copolyesters with Tunable Properties and Degradability

Biomacromolecules, Год журнала: 2025, Номер unknown

Опубликована: Март 8, 2025

Production of high-performance polyesters with tailored degradability remains a challenge. Here, series poly(ethylene-co-isosorbide terephthalate) (PEIT) copolyesters were synthesized by varying the isosorbide (IS) content (0–20 mol %) using tetrabutyl titanate (TBT) as catalyst. By variation IS content, thermal, mechanical, and optical properties effectively tailored. As increased, Tg was raised from 80 to 101 °C, tensile strength 58.8 68.7 MPa. Moreover, excellent transparency maintained (up 90% light transmittance). Interestingly, susceptibility hydrolytic degradation significantly enhanced incorporation IS, PEIT-20 showing approximately 3.5 times higher weight loss compared PET after 50 days alkaline in 0.1 M NaOH solution. This outlines an attractive approach for developing tunable rates, suitable applications transparent thermal packaging materials.

Abstract Conventional chewing gum (CG) consisting of sweeteners and unbiodegradable base (CGB) has caused severe pollution to the environment. To address this issue, work designs synthesizes a partially crosslinked biobased biodegradable polyester elastomer replace high molecular weight rubber in traditional CG for elasticity, along with resin glass transition temperature ( T g ) ≈38 °C provide plasticity CG. Subsequently, is prepared. Poly(1,3‐propanediol/glycerol/sebacate/succinate) (PPGSeSu) elastomers adjustable gel content good elasticity are synthesized by adjusting glycerol, poly(2,3‐butanediol/isosorbide/succinate) (PBIS) resins 8–65 prepared tuning molar ratio isosorbide 2,3‐butanediol. As result, fully biobased, similar performance that commercially available ones achieved using PPGSeSu‐25%P (with 8.58% content) PB 50 I S = 38 °C). The biodegradation rate new 75.52% after 97 d, its properties comparable those according texture profile analysis results.
