Firstly, graphene oxide (GO) was obtained by a modified Hummers method $ ^{36} $ as shown in Figure 2. Briefly, NaNO $ _{3} $ (1.0 g) was added in portions to a flask containing concentrated H $ _{2} $SO $ _{4} $ (70 mL) and then graphite powder (1.0 g) was added followed by addition KMnO $ _{4} $ (6.0 g). The resulted mixture was kept in an ice bath and magnetically stirred for two hours. When the mixture turned to dark green, the reaction was carried out at room temperature for 3 days under magnetic stirring. After that, 100 mL deionized water and 8 mL H $ _{2} $O $ _{2} $ (30%) were added slowly and the system temperature was kept below 20 °C. When the mixture changed to bright yellow, 400 mL HCl (10%) was added under stirring. The resultant brown product was centrifuged and subjected to dialysis with deionized water for 4 days to completely remove all the metal ions and acids.

It is useful for both electrically conductive and non-conductive materials. The X-ray photoelectron spectroscopy of the G4 sample is shown in Figure 6. It can be seen that the binding energy at 287 eV and 533 eV correspond to C1s and O1s in the gel, and the binding energy of N1s is found at 400 eV. The peak positions and the satellite peaks for the Fe 2p1/2 and Fe 2p3/2 depend on sensitively to the oxidation states of Fe.³⁹ The peaks at 708 eV and 724 eV are assigned to the Fe 2p3/2 and Fe 2p1/2 signals, respectively (Figure 6(b)). The satellite peak obtained at 719.9 eV is distinguishable and is a satellite peak for Fe 2p1/2. Besides, there appears another satellite peak at 729.3 eV; this may be a satellite peak for Fe 2p1/2. The presence of the peak at 724 eV and the satellite peak at 737.1 eV confirmed the existence of Fe(III). The satellite peak at 713.4 eV for Fe 2p3/2 was observed. The presence of this 'shoulder' satellite peak and the binding energy difference between the Fe 2p3/2 peak and the satellite peak being approximately 6 eV is the clear evidence of the existence of Fe(II).⁴⁰ The peaks at 708 eV and 719.9 eV confirmed the existence of Fe(0). These results indicate that metallic iron is formed by the reduction effect of RGO or residual hydrazine hydrate while preparing RGO.

A proper amount of RGO is very important for the balance between physical cross-linking degree and the electrical conductivity. Figure 13 shows the equilibrium swelling degree of the prepared gels in 0.01 mol·L⁻¹ Ce₂(SO₄)₃ solution and 0.01 mol·L⁻¹ Ce(SO₄)₂ solution with the same ionic strength, respectively. The gels appear blue when the catalyst Fe(phen)₃ moiety in the oxidized state and red when it in the reduced state. The redox states of Fe(phen)₃ moiety alter the swelling ratio of the gel for the hydrophilicity of the polymer chain increasing with more positive charges. It can be seen that the equilibrium swelling degree of Fe(phen)₃ in the oxidation state in the gel is greater than which in the reduced state.
