Abstract
In order to develop a new type of energetic material that is green and sustainable,nitrated chitosan,the nitrate derivative of chitosan,was synthesized using non deacetylated chitosan as the raw material.The effects of different reaction systems and conditions on the structure,morphology,and properties of nitrated chitosan were compared,and the optimal process parameters were selected.The product was characterized by elemental analysis,scanning electron microsco-py(SEM),laser particle size analysis,and Fourier transform infrared spectroscopy(FTIR).The thermal stability and thermal decomposition performances of the products were studied by differential scanning calorimetry(DSC).The results indicate that the particle morphology of the product obtained from the nitration reaction in acetic anhydride-nitric acid sys-tem was uniform and has a higher nitrogen content.The nitrated chitosan treated by ethanol reflux exhibits excellent thermal stability,with a thermal decomposition peak temperature of 211.9℃and an apparent activation energy of 315.491 kJ/mol obtained by non isothermal DSC analysis.At the same time,the calculation of decomposition enthalpy shows that the nitra-ted chitosan washed by alcohol in acetic anhydride-nitric acid system has an energy level equivalent to that of nitrocellulose.关键词
