Architectural Engineering of Semi-Crystalline Elastomers — •Sergei Sheiko — University of North Carolina at Chapel Hill, USA

Molecular assembling, including polymer crystallization and hydrogen bonding, is an effective tool for creating moldable and dynamic networks with unique physical properties such as reversible and time-programmable shape memory. Unlike linear polymer melts, the crystallization process of polymer networks is guided by the network architecture described by the mesh dimensions and branching of the network strands. Synthetic control of architectural parameters allows for accurate variation of the degree of crystallinity, physical crosslink density, and crosslink functionality. We will discuss different examples of the architectural control of structure-property correlations for different types of polymer networks including super-soft and super-elastic brush-like elastomers and linear-chain elastomers that display reversible shapeshifting.
