Table 2 Mechanical properties of Na-CMC–PAAm (blend) and the blend loaded with α-Fe2O3, GO and CuO: Tensile modulus (\({E}_{\mathrm{t}}\)), Tensile strength (\({\sigma }_{\mathrm{M}}\)), Strain at tensile strength (\({\varepsilon }_{\mathrm{M}}\)), Stress at break (\({\sigma }_{\mathrm{B}}\)), Strain at break (\({\varepsilon }_{\mathrm{B}}\)), and toughness. Each value represents mean ± standard error (SE).
