Time–Temperature Superposition of Polybutadiene Vitrimers [PDF]
Macromolecules, 2023 A vitrimer has covalent cross-links that preserve network connectivity but permit topology fluctuations through dynamic exchange reactions. In this work, we investigate the linear rheology of polybutadiene (PB) vitrimers bearing cross-links that exchange via dioxaborolane metathesis.

The Formation of All-Silk Composites and Time-Temperature Superposition. [PDF]
Materials (Basel), 2023 Extensive studies have been conducted on utilising natural fibres as reinforcement in composite production. All-polymer composites have attracted much attention because of their high strength, enhanced interfacial bonding and recyclability. Silks, as a group of natural animal fibres, possess superior properties, including biocompatibility, tunability ...
