(a) Molecular structures of ETPTA (x+y+z=20) and PEGDA (x=12) oligomers. (b) Differential scanning calorimetry plot of a macroporous ETPTA-co-PEGDA copolymer with 1:3 ratio. (c) Typical force–depth indentation curve used to measure elastic properties of SMP. (d) Average Young’s moduli for PEGDA, ETPTA-co-PEGDA copolymer with 1:3 ratio and ETPTA polymers.
