Poly(3-hydroxybutyrate) (PHB) has gain in recent years a huge interest the food packaging field due to its renewable origin from waste as well non-food crops, high mechanical strength, medium-to-high barrier performance, and inherent biodegradability natural environments. Despite these advantages, PHB also shows narrow processing window brittleness since this homopolyester low thermal stability crystallinity, limiting industrial application. The present review provides an updated state of art most relevant aspects terms properties materials with particular emphasis for their use sustainable packaging. It describes potential strategies that can be applied improve both processability PHB, including melt blending green plasticizers flexible biodegradable polymers development more ductile co-polyesters. Finally, management newly developed PHB-based articles is discussed, compostability develop biopolymers economically favored alternatives such chemical recycling technologies.

The incorporation of insulating polymers into conjugated has been widely explored as a strategy to improve mechanical properties flexible organic electronics. However, phase separation due the immiscibility these limited their effectiveness. In this study, we report discovery multiple non-covalent interactions that enhances miscibility between and polymers, resulting in improved properties. Specifically, have added polyvinyl chloride (PVC) polymer PM6 observed significant increase solution viscosity, indicative favorable two polymers. This phenomenon rarely other insulating/conjugated composites. Thin films PM6/PVC exhibit much-improved crack-onset strain 19.35 %, compared 10.12 % for pristine films. Analysis reveal "cyclohexyl-like" structure formed through dipole-dipole hydrogen bonding PVC acted cross-linking site thin films, leading Moreover, blend demonstrated excellent thermal bending stability when applied an electron donor solar cells. These findings provide new insights can be utilized enhance may potential applications

Thermal recycling strategy of Coca-Cola PVC label films by its co-carbonization with Terminalia ivorensis leaves

Cleaner Engineering and Technology, Год журнала: 2022, Номер 11, С. 100564 - 100564

Опубликована: Окт. 1, 2022

The Coca-Cola company utilizes PVC label films for its product packaging, which may be due to their high physicochemical durability. However, these are less recycled in comparison with other plastics release of chlorine-based chemicals, leading environmental pollution on a global scale. In this study, were co-carbonized Terminalia ivorensis leaves (TIL) top-lit updraft reactor produce biochar. properties the PVC-impregnated biochar (TIL-PVC-biochar) compared those (TIL-biochar), using SEM-EDX, FTIR, BET analysis, and DTA/TGA study effect material. carbonization process, ran duration 100 min, gave yield 42.50% 45.60% TIL-biochar TIL-PVC-biochar, respectively. EDX result confirmed success impregnation process an increased concentration carbon chlorine TIL-PVC-biochar. SEM indicates presence good interfacial bonding around thermo-chemically disintegrated particles. analysis showed that reduced surface pore TIL-PVC-biochar had area diameter 194 m2/g 2.088 nm, FTIR contained functional groups such as hydroxyl, carbonyl, carboxylic, alkene, alkyne groups. It also chlorine. was more thermally stable than TIL-biochar. make it material production conductive composites adsorbent sequestration pollutants from environment.

Abstract Plasticizers are widely used in poly(vinyl chloride) (PVC), polylactic acid (PLA), thermoplastic starch (TPS), and other modified powder materials to enhance the flowability, flexibility, processability of macromolecules. Because reprotoxicity phthalates animals humans, certain have recently been banned United States Europe. Biobased plasticizers from green biomass–derived renewable resources with low toxicity expected be a substitute for phthalates. Among variety newly developed biobased monomers, cardanol, isosorbide two most promising because their unique structural features. This review summarizes research progress cardanol‐ isosorbide‐based synergistic effects plasticization, thermal stabilization, anti‐migration. By summarizing analyzing relationship between molecular structure plasticizer plasticizing performance, this can provide theoretical guidance future on design isosorbide‐ cardanol‐based plasticizers. Highlights replace The effect single is not good. required. There exists trade‐off weight compatibility. Epoxidized ester as heat stabilizer.
