项目摘要
In this study, the nano structure of carbon materials including activated carbons which contain ultra micro pores of under 0.7 nm in the size was analyzed by high resolution transmission electron microscopy(HRTEM), simulation and image processing.Amorphous carbon films are observed by HRTEM on different defocus values (Δfs) in order to determine the phase contrast transfer function of objective lens of the HRTEM with consideration with damping property as well as simulation of the transfer function. Power spectra of the HRTEM images of the amorphous carbon film obtained by 2 dimensional fast Fourier transform (2D-FFT) were compared to the simulation data. The structure of carbon materials can be known to be analyzed by integration their power spectra around the center point obtained by 2D-FFT of the HRTEM image. This method was applied to analyzing polypharaphenylene based carbons, pitch based carbons, and carbon nanofibers.The analysis method was also applied to a carbon molecular sieve and other activated carbons, and compared to gas adsorption. The carbon molecular sieve which contains ultramicropore could not adsorb N_2 or Ar but can CO_2 with high-pressure. Pore size distribution obtained by the HRTEM and image analysis method was compared to results of the gas adsorption. The HRTEM image depends on the transfer function of objective lens of the HRTEM in high-resolution observation. The transfer function is important for exact observation of amorphous structured materials such as activated carbons. The HRTEM combined with image analysis was shown to be useful for structural analysis of ultramicropore and was expected to be an independent technique for confirmation of gas adsorption usefulness. The analysis method of amorphous like carbons can be improved through this research.
本研究利用高分辨电子显微镜、模拟和图像处理技术分析了含超微孔尺寸在0.7 nm以下的炭材料的纳米结构,并用高分辨电子显微镜观察了不同离焦值(Δf)下的无定形碳膜,以确定考虑阻尼性的高分辨电子显微镜物镜的相衬传递函数,并对传递函数进行了模拟。将二维快速傅里叶变换(2D-FFT)获得的非晶碳膜的HRTEM图像的功率谱与模拟数据进行了比较。碳材料的结构可以通过积分它们在HRTEM图像的2D-FFT获得的中心点附近的功率谱来分析。将该方法应用于聚苯基碳、沥青基碳和碳纳米纤维的分析,并将该分析方法应用于碳分子筛和其他活性碳,并与气体吸附进行了比较。含有超微孔的碳分子筛不能吸附N_2或Ar,但能在高压下吸附CO_2。用HRTEM和图像分析方法得到的孔径分布与气体吸附的结果进行了比较。在高分辨率观测中,HRTEM成像依赖于HRTEM物镜的传递函数。传递函数对于准确观察非晶态结构材料(如活性碳)是很重要的。HRTEM与图像分析相结合可用于超微孔结构分析,有望成为确认气体吸附有用性的一种独立技术。通过本研究,可以改进无定形类碳的分析方法。
