(A) the effect of pH on the N/C of reaction products between GOs and L-Proline, N/C was determined by elemental analyzer, pH is 1, 3, 5, 9 and 12. N/C is the ratio of N to C content in GO-amino acids. (B) the effect of temperature on the N/C of reaction between GOs and L-Proline, temperature is 50, 70, 90, 110 and 160 °C. N/C is the ratio of N to C content in GO-amino acids. (C) the XRD of composite between amino acids and GOs, samples were prepared in pH of 3 at 90 °C. (D) the FTIR Spectrometer of composite between amino acids and GOs, samples were prepared in pH 3 at 90 °C.
