Energy storage in thermoset shape memory polymers happens through entropy reduction during the programming step, but low energy release is known to be a bottleneck for wide-spread application. Here, the authors show a thermoset network that stores energy primarily through enthalpy increase by bond length change, which leads to an improved energy output.
