SOL-GEL-SUPERCRITICAL SYNTHESIS AND PROPERTIES OF NITROCELLULOSE/GLYCIDYLAZIDE POLYMER/PENTAERYTHRITOL TETRANITRATE NANOCOMPOSITES
RESUMO
Nitrocellulose/glycidylazide polymer/pentaerythritol tetranitrate (NC/GAP/PETN) nanocomposite energetic materials were successfully fabricated by sol-gel and supercritical drying methods. The microstructure of the nanocomposite was analyzed by scanning electron microscopy (SEM), infrared (IR), X-ray diffraction, and X-ray photoelectron spectroscopy. SEM pictures showed that the NC/GAP skeleton had nanoporous structure, and the PETN particles were enveloped in the gel skeleton. PETN did not undergo a phase transition during the reaction, and the molecular structures of NC, GAP, and PETN did not transform. The specific surface area of NC/GAP matrix was much higher than nanocomposite with PETN. Differential scanning calorimetry-IR was used to study the decomposition products of NC/GAP/PETN, and the main products contain CO2, N2O, and such. The energy performance was calculated, and the results implied that the energy performance will be higher as the content of NC increases. The results of the impact sensitivity and friction sensitivity tests show that the safety of nanocomposites becomes higher with the content of GAP increasing.
