Comparable results have been reported by Cho et al., who measured a Young's modulus for GO/SF composite films of 22 GPa using a nanoindentation method. Further, Hu et al. conducted bulge and buckling tests on GO/SF membranes and reported increasing values of Young's modulus from ∼10 GPa to ∼145 GPa with increasing fractions of GO, ranging from 0 to 23.5 % (v/v). Comparable to our findings, they measured a modulus of ∼25 GPa at a GO volume fraction of ∼3 % (v/v). For comparison, Suk et al. reported Young's moduli of up to ∼207 GPa for pure GO monolayers. For pure SF, Young's moduli ranging from 4 to 22 GPa have been reported. Additionally, we reported a Young's modulus of ∼5 GPa for membranes from TNRs, which were crosslinked by 1,12-dodecanedioc acid. .
