In addition, we demonstrated that our polyamide network resisted creep deformation at elevated temperatures. As shown in Figure , our polyamide network polymers only exhibited 1.5-5% creep strain at temperatures from 100 to 200 °C for 50 mins. Note that this strain also included thermal expansion. In comparison, the linear polyurea actuators reported (grey dashed line, Figure ) exhibited viscous flow- reaching 300% strain in 35 minutes at 100 °C (above its Tg). In terms of solvent resistance, the polyamide network swelled in dichloromethane (DCM) -with ~100% mass increase -but recovered to the original shape after drying (Table ). In comparison, the thermoplastic polyurea dissolved in chloroform. We demonstrated that ductile glassy networks could be polymer actuators with high actuation stresses, creep resistance, and solvent resistance.
