Mechanical properties of cryogels synthesized in this study.

Cryogel	Compressive strength, ${\delta }_{\mathit{max}}$ [kPa]	Young’s modulus, $\mathrm{E}$ [kPa]	Yield strength, $\sigma$ [kPa]
Freeze drying
SFO:PEI	132.97	$1.052$	$1.81$
SFO:SiO2-0.08–3	95.69	$0.909$	$2.00$
SFO:PEI:SiO2-0.08–3	131.76	$0.873$	$3.37$

The samples are named as SFO:PEI:SiO₂-x–y (where x and y refers to the concentration of TEOS and pH, respectively).
