Abstract
Shape memory polymers (SMP), methods of making shape memory polymers, and articles including shape memory polymers are provided. The SMPs include thermoset polymer networks formed from an epoxy and a diamine. The SMPs can be in particle form and can be added to other materials while maintaining expansion capabilities. Articles formed from the SMPs can include rebar.
Claims21
