Ring-Opening Polymerization of Lactones to Prepare Closed-Loop Recyclable Polyesters

Macromolecules, Journal Year: 2024, Volume and Issue: 57(5), P. 1919 - 1940

Published: Feb. 22, 2024

The large production and indiscriminate disposal of plastics have resulted in serious resource global environmental crises, which has raised a demand to develop more sustainable circular economy. An ideal strategy address the end-of-life issue is next-generation polymers with closed-loop life cycles, can be selectively depolymerized back monomers at end their service life. Aliphatic polyesters prepared by ring-opening polymerization (ROP) moderately strained lactones shown great potential recyclable polymers. This Perspective highlights recent achievements for that are derived from four-, five-, six-, seven-membered focusing on discussion thermodynamic kinetic considerations, monomer design principles polymer preparations, material properties, chemical recyclability. Finally, current challenges possible directions also discussed.

Designed to Degrade: Tailoring Polyesters for Circularity

Chemical Reviews, Journal Year: 2024, Volume and Issue: 124(13), P. 8473 - 8515

Published: June 27, 2024

A powerful toolbox is needed to turn the linear plastic economy into circular. Development of materials designed for mechanical recycling, chemical and/or biodegradation in targeted end-of-life environment are all necessary puzzle pieces this process. Polyesters, with reversible ester bonds, already forerunners circularity: poly(ethylene terephthalate) (PET) most recycled material suitable and while common aliphatic polyesters biodegradable under favorable conditions, such as industrial compost. However, circular design needs be further tailored different options enable recycling greener conditions rapid enough even less environmental conditions. Here, we discuss molecular polyester chain targeting enhancement circularity by incorporation more easily hydrolyzable additional dynamic or degradation catalyzing functional groups part chain. The utilization replacement current volume plastics also reviewed well embedment green catalysts, enzymes matrices facilitate

Functional Nanocellulose, Alginate and Chitosan Nanocomposites Designed as Active Film Packaging Materials

Polymers, Journal Year: 2021, Volume and Issue: 13(15), P. 2523 - 2523

Published: July 30, 2021

The aim of the study was to characterize and compare films made cellulose nanocrystals (CNC), nano-fibrils (CNF), bacterial nanocellulose (BNC) in combination with chitosan alginate terms applicability for potential food packaging applications. In total, 25 different formulations were evaluated, seven biopolymer best mechanical performance (tensile strength, strain)—alginate, 5% CNC, chitosan, 3% BNC without glycerol, CNF glycerol—were selected investigated regarding morphology (SEM), density, contact angle, surface energy, water absorption, oxygen barrier properties. Studies revealed that polysaccharide-based added CNC are most suitable purposes, better dispersing than observed. Results showed an increase hydrophobicity (increase angle reduced moisture absorption) addition had highest 108 ± 2, 15% lower absorption compared pure chitosan. Overall, ability additives preserve structure function materials a humid environment convincingly demonstrated. Barrier properties improved by combining biopolymers, vapor transmission rate (WVTR) 15–45% permeability (OTR) up 45% adding single formulations. It concluded good barrier, is comparable PLA, properties, would be alternative conventional plastic used ready-to-eat foods short storage time.
