摘要
Abstract
By using 1,2-epoxypropane as the agent for speeding up the hydrolyzation of Fe(Ⅲ) ions, AND/Fe2O3 composite wet gel was prepared by sol-gel method under a mild and nontoxic condition. Consequently, the AND/ Fe2O3 aerogel was obtained by means of supercritical CO2 fluid extraction. TEM,SEM,EDS,IR,DSC and sensitivity test were employed to characterize the appearance, structure, thermal behaviour and mechanical sensitivity of the samples. The results indicate that the as-prepared AND/Fe2O3 nanoparticles are about 50- 100 nm in diameter. As the decrease of the mass of AND,the nanocomposites become much insensitive to mechanical stimuli. Moreover,the AND/Fe2 O3 nanoparticles decomposes at lower temperature with the disappearance of melting endothermic peak.关键词
