摘要:
以甲基三乙氧基硅烷作为前驱体,碳纳米管为添加物,采用溶胶-凝胶法和常压干燥制备碳纳米管掺杂改性的柔性SiO2气凝胶。通过扫描电子显微镜(SEM)、傅里叶变换红外光谱(FT-IR)、热重-差示扫描量热仪(TG-DSC)及机械测试对制备的气凝胶进行表征,研究碳纳米管对柔性SiO2气凝胶性能的影响。结果表明:碳纳米管的添加有效地增加了柔性SiO2气凝胶的强度,柔性气凝胶的热稳定性从455 ℃提高到563 ℃,并提高了气凝胶的使用性能。
Abstract:
With carbon nanotubes as the additive,the flexible silica aerogels incorporated with carbon nanotubes. The precursor was methyltriethoxysilane and was prepared by the sol-gel technology.The ambient drying was used.Scanning electron microscopy(SEM),Fourier transform infrarespectroscopy(FT-IR),thermogravimetric and differential analysis(TG-DSC),and mechanical test were used to characterize the as-synthsized aerogels.Results showed that the compressive strength of flexible aerogel was improved and the thermal stability of flexible aerogel was enhanced from 455 ℃ to 563 ℃.The service performance was correspondingly enhanced.
