From: Bio-inspired self-healing and anti-corrosion waterborne polyurethane coatings based on highly oriented graphene oxide

Fig. 1

a Molecular design and chemical structure of WPU. b Schematic diagram of WPU and its self-assembled network. c Particle size distribution of WPU (the optical photograph of the WPU was shown in the illustration). d Transmittance of WPU in the visible range (The optical photograph of flowers and plants captured through WPU was shown in the illustration). The e synchronous and f asynchronous 2D-related FT-IR spectra of WPU were calculated from 30 to 160 °C.
