Similar to typical elastomers, during programming, the work applied to the material was stored in the material, which was then released as work to the surroundings as the chains were able to relax at elevated temperatures. This differs from typical elastomers, where elastic recovery occurs in a short timeframe; here, the glassy networks shows elastic recovery occurs in a near-infinite time frame at T<Tg. In other words, these ductile glassy networks are elastomers in a glassy state at ambient conditions. The elastic recovery in the time domain is currently being studied in our group and will be reported elsewhere. Furthermore, we demonstrated the polymers' capability of performing work by lifting a heavy object (Figure ). A dogbone specimen (f=2.25 polymer) was strained at 200%, then mounted vertically with a wrench that is 1000x heavier than the sample. The specimen recovered 95% of the strain while lifting the weight.
