Polyurethane - Dispersed Diazo Black GNN Polymer dye (PU-DDB GNN) was synthesized by incorporation of DDB GNN into polyurethane chains. The expected structure of polyurethane-dispersed diazo black GNN polymer dye was confirmed by FT-IR and UV-vis spectra. The photochromic phenomenon of polyurethane-dispersed diazo-black GNN dyes was investigated. And through the thermogravimetric analysis and differential calorimetry analysis, it is confirmed to be an amorphous structure with good thermal stability. Through the test of its mechanical properties, the results show that the elongation at break is quite high.
