at 650◦C. This phenomenon indicates the existence of inorganic substances in WNP, p-WNP and Film. After the filtration of the p-WNP/AmimCl solution, most of the inorganic substance was removed, so the f-Film gave a less residue weight than WNP, p-WNP and Film. This result accords with the XRD and FTIR results in Figs. 3 and 4.
