A redox polymer ferrocene-modified polyacrylamide (PAM-Fc) was prepared by using post-modification technology to modify polyacrylamide with grafted ferrocene functional groups in alkylation reaction in dimethyl sulfoxide directly.Chemical structure

electrochemical activity and rheological properties of PAM-Fc in aqueous solutions were investigated respectively.It was found that the thermal stability and redox property were improved significantly and the viscosity of PAM-Fc aqueous solutions increased obviously compared with pure PAM due to the hydrophobic association of Fc groups.Fc groups can stabilize the free radical of PAM polymer chains to improve the thermal stability of PAM-Fc.Furthermore

the viscosity of PAM-Fc aqueous solutions can be adjusted by adding NaCl which can shield the charge on the PAM-Fc molecule chains

-cyclodextrins being a host material which can entrap Fc groups and H2O2 which can oxidize Fc from reduction state to oxidation state and turn hydrophobic Fc to hydrophilic Fc.
