Abstract: The disclosure relates to shape memory polymer (SMP) networks formed using acrylate-based monomers. As disclosed herein, proportional dependence between toughness and C? value may be broken in acrylate-based shape memory polymers comprising mono-functional acrylates which are controllably crosslinked using a crosslinker such as poly(ethylene glycol) di-methacrylate (PEGDMA) with an average molecular weight of 550 (PEGDMA 550). Through the controlled addition of a crosslinker, the relationship between the C? value and toughness can be manipulated (e.g., proportional relationships may be destroyed and/or reversed) in acrylate-based SMP networks.
