Novel triol-crosslinked polyurethanes and their thermorheological characterization as shape-memory materials
Abstract A new family of crosslinked polyurethanes was synthesized and characterized as shape-memory polymers. Three-arm network junctions are provided by 1,1,1-trimethylol propane with an isocyanateExpand

Strain softening of nano-scale fuzzy interfaces causes Mullins effect in thermoplastic polyurethane
The strain-induced softening of thermoplastic polyurethane elastomers (TPUs), known as the Mullins effect, arises from their multi-phase structure. We used the combination of small- and wide- angleExpand
