Rheology test of PNAGA‐PCBAA‐10‐4, PNAGA‐PCBAA‐15‐4, and PNAGA‐PCBAA‐20‐4 hydrogels. Variation of dynamic storage moduli G′ and loss moduli G′′ in A) a temperature amplitude sweep test from 25 to 70 °C and in B) a frequency sweep test from 0.01 to 10 Hz at 37 °C. Viscosity measurement of PNAGA‐PCBAA‐b‐4 (b = 10, 15, and 20) at 37 °C in C) a shear rate sweep from 0.01 to 500 s−1. The variation in G′ and G′′ values of PNAGA‐PCBAA‐b‐4 (b = 10, 15, and 20) hydrogels measured with an alternate step strain being switched from small strain (γ = 10%) to large strain (γ = 200%, 400%, and 600%) at D–F) a fixed angular frequency (1 Hz). Each strain interval was kept as 100 s.
