摘要：
To elucidate the molecular structure evolution and plasticizing mechanism of nitrocellulose (NC) matrix composites during plasticizing process, samples with different plasticizing stages were prepared and analyzed by two-dimensional correlation infrared spectroscopy. The results of PCMW2D analysis show that the plasticization of NC matrix composites can be divided into three stages according to the movement of functional groups, named stage I, II and III respectively. Further correlation analysis for each stage shows that the interaction between NC and NG is completely different in each stage: In Stage II, hydrogen bonds and hydroxyl groups of NC take the lead in a large degree of movement, reflecting the violent interaction between NC and NG under external plasticization conditions. Because of the unique sequence of motion correlation of the characteristic functional groups of NC and NG, the results of this study can be used as a reference to directly test the samples with unknown plasticization degree and make accurate judgment, which provides a new method and experimental basis for revealing the plasticizing mechanism of NC matrix composites. © 2020, Editorial Board of Journal of Explosives & Propellants.
