Macroscopically, as 𝑓 increases, 𝐺' becomes much larger than 𝐺'' over a wide range of shear frequency (Fig. ) and the loss factor becomes smaller (Fig. ), suggesting that the network becomes less dissipative. However, the network stiffness increases by more than two orders of magnitude from ~10 kPa to ~3 MPa (Fig. ). As a result, although the network becomes less stretchable (Fig. ), the tensile toughness increases by nearly 40 times from 28±2.42 kJ/m 3 to 1.2±0.12 MJ/m 3 (Fig. ).
