摘要
The safe storage of nitrocellulose has become challenging due to their requirements of extreme storage environments, and existing stabilizers cannot fully meet the demand. Thus, developing new high-performance stabilizers to improve the stability of nitrocellulose is urgently needed. Considering the stabilizing mechanism of stabilizers and the excellent free radical scavenging ability of fullerenes, two novel fullerene-based stabilizers, pentaacyloxyphenyl fullerene derivatives (PAOP-C60), were designed and synthesized, and their structures were characterized by FTIR, UV–Vis and NMR. The thermal action of PAOP-C60 during thermal decomposition process of nitrocellulose was studied by thermal analysis, which indicating that the thermal stability of nitrocellulose was increased with addition of PAOP-C60 and the PAOP-C60 was found to exhibit superior thermal stability than traditional stabilizer. The results of electron spin resonance showed that fullerene-based stabilizers had a significant scavenging effect on nitrogen oxide radicals, and the IC50 of PAOP-C60 (0.674–0.818 g L−1) was smaller than that of diphenylamine (1.717 g L−1). Moreover, the intermediate product produced by PAOP-C60 and nitrocellulose action was extracted and characterized by FTIR. A possible stabilization mechanism of PAOP-C60, which was different from traditional stabilization mechanism, was proposed.
