摘要：
The metal particles are introduced into the polymer chain by the sol-gel method. The porous metal-containing polymer material, which is obtained by freeze-drying, has the features of fluxion, large specific surface area and porosity. These features not only restrain the agglomeration of nano-metal catalyzer, but also provide sufficient catalytic active sites. Two kinds of porous metal-containing polymers (PAA-Cu and PAA-Pb) were prepared. Scanning electron microscope, transmission electron microscopy, infrared spectroscopy, and Brunauer-Emmett-Teller method are used to characterize PAA-Cu and PAA-Pb. TG-IR-GC-MS combination is used to analyze the catalysis of PAA-Cu and PAA-Pb on the thermal decomposition of ammonium perchlorate (AP). The results indicate that the decomposition peak temperature of AP is decreased to 143.1℃ under the catalysis of PAA-Cu and 73.7℃ under the catalysis of PAA-Pb. Porous PAA-Cu which is of better catalysis compared with PAA-Pb was calcined in this paper. Cu and Cu2O are produced by in-situ decomposition, while the increasing porosity promotes the exposure of catalytic active substances. The new features obtained by calcination make for the catalysis on thermal decomposition of AP. © 2021, Editorial Board of Acta Armamentarii. All right reserved.
