Chemical Recycling of Step-Growth Polymers Guided by Le Chatelier’s Principle

ACS Engineering Au, Год журнала: 2024, Номер 4(5), С. 432 - 449

Опубликована: Июль 15, 2024

Although step-growth polymers (SGPs) play a fundamental role in the plastics economy, contributing significantly to various facets of our daily life, their end-of-life management remains inadequately addressed. Chemical recycling SGP wastes, involving depolymerization followed by repolymerization, emerges as promising solution toward achieving circular economy. The SGPs is usually dynamic equilibrium with polymerization reactions, thus falling under system amenable Le Chatelier's principle. This perspective endeavors elucidate interplay between principle and chemical particular emphasis on guidance provided latter process. To this end, we have selected five conventional SGPs, namely, poly(ethylene terephthalate), polyamides, polycarbonates, polyurethanes, polyureas, representatives how alterations temperature, pressure, concentrations products or reactants, catalysts influence process SGPs. Additionally, proposes several potential strategies for applying

Topological Transition in One-Dimensional π-Conjugated Polymers via Strain Engineering

ACS Macro Letters, Год журнала: 2025, Номер unknown, С. 329 - 334

Опубликована: Фев. 25, 2025

Topological trivial and nontrivial phases can be readily realized in low-dimensional organic polymers via bottom-up synthesis. However, to effectively harness these topological practical devices, it is crucial develop strategies for achieving a controllable transition. Inspired by topology π-electron pairing, we propose method induce transitions through orbital crossover driven continuous external strain 10 one-dimensional (1D) π-conjugated (CPs), categorized into aromatic quinonoid forms. Our results reveal that exhibit edge states, indicative of (Zak invariant, Z2 = 1), while correspond (Z2 0). Notably, the poly(thiophene dioxide) (TDO) polymer undergoes reversible transition under tensile 3.6%, demonstrating strain-dependent phase. This phenomenon attributed gap closure resulting from between highest occupied molecular (HOMO) lowest unoccupied (LUMO). work uncovers 1D highlights induced engineering.

Sequence-controlled alternating block polychalcogenophenes: synthesis, structural characterization, molecular properties, and transistors for bromine detection

Chemical Science, Год журнала: 2023, Номер 14(32), С. 8552 - 8563

Sequence-controlled polychalcogenophenes have attracted much interest in terms of synthesis, structure and function polymer science. For the first time, we developed a new class alternating block conjugated copolymers denoted as poly(alt-AB)x-b-(alt-AC)y where both blocks are constituted by an copolymer. 3-Hexylthiophene (S), 3-hexylselenophene (Se) 3-hexyltellurophene (Te) used A, B C units to assemble three sequence-controlled P(SSe)b(STe), P(SSe)b(SeTe) P(STe)b(SeTe) which prepared adding two different Grignard monomers sequence carry out Ni(dppp)Cl2-catalyzed Kumada polymerization. The molecular weight, dispersity, length each (x = y) main-chain can be synthetically controlled via catalyst transfer polycondensation mechanism. structures, i.e. main chain with high side-chain regioregularity, unambiguously confirmed 1H-NMR 13C-NMR. optical electrochemical properties polymers systematically fine-tuned composition ratio chalcogenophenes.

Radical chemistry in polymer science: an overview and recent advances

Beilstein Journal of Organic Chemistry, Год журнала: 2023, Номер 19, С. 1580 - 1603

Опубликована: Окт. 18, 2023

Radical chemistry is one of the most important methods used in modern polymer science and industry. Over past century, new knowledge on radical has both promoted been generated from emergence synthesis modification techniques. In this review, we discuss four interconnected aspects. We begin with polymerization, employed technique for industrial production polymeric materials, other involving a process. Post-polymerization modification, including crosslinking surface key process that introduces functionality practicality to materials. depolymerization, an efficient approach destroy polymers, finds applications two distinct fields, semiconductor industry environmental protection. Polymer largely diverged organic fine division but chemists constantly acquire inspirations chemists. Dialogues between communities will deepen understanding fields benefit humanity.
