Abstract

According to the good conductivity and electrocatalytic activity of nano platinum and multi-walled carbon nanotubes (MWCNTs) and the hydrogel properties of polyvinyl alcohol (PVA), MWCNTs and PVA double-network porous hydrogels were designed and prepared. The surface of the conductive hydrogel electrode film formed a three-dimensional porous structure, and the stacking of the PVA-coated MWCNTs formed a nanoscale micropore structure. However, the micropore network structure inside the electrode film was not obvious, which was the reason why the electrode film did not selectively catalyzed glucose. The elastic modulus of PtNPs/MWCNTs/PVA electrode film is consistent with that of PVA. Its modulus of elasticity is close to that of human tissue.
