Sustainable Supramolecular Polymers

This article outlines the challenges and prerequisites for developing sustainable supramolecular polymers. It argues that, by achieving a delicate equilibrium between toughness and recyclability, as well as between stability and healing capabilities, transient supramolecular polymers hold promise as an attractive option for the forthcoming generation of eco-friendly materials.

Abstract

Polymer waste is a pressing issue that requires innovative solutions from the scientific community. As a beacon of hope in addressing this challenge, the concept of sustainable supramolecular polymers (SSPs) emerges. This article discusses challenges and efforts in fabricating SSPs. Addressing the trade-offs between mechanical performance and sustainability, the ultra-tough and multi-recyclable supramolecular polymers are fabricated via tailoring mismatched supramolecular interactions. Additionally, the healing of kinetically inert polymer materials is realized through transient regulation of the interfacial reactivity. Furthermore, a possible development trajectory for SSPs is proposed, and the transient materials can be regarded as the next generation in this field. The evolution of SSPs promises to be a pivotal stride towards a regenerative economy, sparking further exploration and innovation in the realm of sustainable materials.
