Toward a greener future: Exploring sustainable thermoplastic elastomers

Abstract

Thermoplastic elastomers (TPEs) are based on a combination of the properties of plastic and elastomers, such as elasticity and processability. Although TPEs are known to be recyclable and reprocessible, their environmental impact remains a concern. To address this issue, researchers have focused on developing sustainable and environmentally friendly TPEs, synthesized from renewable bio-based sources and capable of decomposing at the end of their lifecycle. Various approaches have been introduced to substitute conventional fossil-based elastomers; however, limitations still exist in terms of mechanical properties, elastic recovery, cost-effectiveness and degradability. In this perspective, previous distinguished related studies are discussed to provide valuable insights and guidance for the development of a novel sustainable TPE in the future.
