Abstract

Mechanical properties of supramolecular elastomers (reversible polymer networks with chains connected by supramolecular and dynamic covalent bonds) differ noticeably from those of conventional elastomers with covalent cross-links. Due to the ability of supramolecular polymers to be reprocessed, reshaped, recycled and reused, they are considered as potential candidates for green and sustainable economy. A simple model is developed for the viscoplastic behavior of supramolecular elastomers at large strains. The model involves only four to five material parameters and describes adequately the response of supramolecular elastomers under tension, compression and cyclic loading in a unified manner. The governing equations are applied to the analysis of experimental stress–strain diagrams on supramolecular elastomers with various types of reversible bonds. Good agreement is revealed between the observations and results of numerical analysis. Correlations are established between types and concentrations of supramolecular bonds and adjustable parameters in the model.
