Application of Dynamic Mechanical Analysis in Characterization of Vitrimers
Vitrimers are booming in macromolecule research field because of the combination of the plasticity of thermoplastic materials and the permanent properties of thermosetting materials.The dynamic viscoelastic and rheological behaviors of these materials can be studied in-depth by dynamic mechanics analysis,contributing to establishing the relationships between vitrimer structures,such as crosslinking networks and dynamic bonds,and material properties.In this short review,applications of dynamic mechanical analysis in the detection of the dynamic viscoelasticity,cross-linking network structures,rheological behavior,expansion and shape memory behavior of vitrimers are summarized,providing a reference for the structural design,performance characterization and processing applications of such materials.
