From Polyester Plastics to Diverse Monomers via Low‐Energy Upcycling

Advanced Science, Journal Year: 2024, Volume and Issue: 11(25)

Published: April 16, 2024

Abstract Polyester plastics, constituting over 10% of the total plastic production, are widely used in packaging, fiber, single‐use beverage bottles, etc. However, their current depolymerization processes face challenges such as non‐broad spectrum recyclability, lack diversified high‐value‐added products, and crucially high energy consumption. Herein, an efficient strategy is developed for dismantling compact structure polyester plastics to achieve diverse monomer recovery. undergo swelling decrystallization with a low barrier via synergistic effects polyfluorine/hydrogen bonding, which further demonstrated density functional theory calculations. The process elucidated through scanning electron microscopy analysis. Obvious destruction crystalline region X‐ray crystal diffractometry curves. PET undergoes different aminolysis efficiently, yielding nine corresponding monomers low‐energy upcycling. Furthermore, four types five blended closed‐loop recycled, affording exceeding 90% yields. Kilogram‐scale real polyethylene terephthalate (PET) waste successfully achieved 96% yield.

Sandwich‐structured light‐transmitting composites based on waste textiles: Fabrication, optical properties, and bending failure behavior

Polymer Composites, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 2, 2025

Abstract Currently, glass fiber‐reinforced resin composites, as an advanced optically transparent material, have garnered widespread attention and research. In the context of new‐era developments, there is a growing demand expectation for visual artistic expression light‐transmitting composites. this study, fiber fabric, silk recycled polyester jacquard fabric were used reinforcement materials, while epoxy was selected matrix material. A green decorative composite with uniform light diffusion soft effects prepared using vacuum bag molding process. By altering woven structure (plain weave, twill satin weave), yarn density, twist optical properties composites can be regulated. The unique triangular cross‐section, structure, large folds plain‐woven particularly conducive to reflection refraction within composite, thereby significantly enhancing Furthermore, bending failure behavior investigated through three‐point tests, acoustic emission (AE) test, micro‐computed tomography (Micro‐CT) scanning. laminate specimens reinforced exhibited best performance, strength modulus reaching 434.4 MPa 19.0 GPa, respectively. combination AE micro‐CT scanning techniques successfully established correlation between signals damage modes. This study identified main modes plain woven, breakage, interlayer delamination, fiber/resin debonding, Highlights Waste textiles use in Silk fabric's weave affected composites' properties. Fiber breakage Plain optimal diffuse light, superior flexural performance.
