Study on evaluation of edges and surface functional groups of carbon materials

Abstract

Qualitative and quantitative evaluation of the edges and functional groups of carbon materials are essential for application to functional materials. The aim of this thesis is to establish those evaluation methods of them. In Chapter 1, the introduction, the edges and surface functional groups of carbon materials, and their conventional evaluation methods were described. In Chapter 2, the decomposition behavior of functional groups of ExCFs (Exfoliated Carbon Fibers) was investigated by using TPD (Temperature Programmed Desorption) and XPS measurements. Chapter 3 summarizes the application of the TPR (temperature-programmed reduction) method to evaluate the edge of carbon materials. Chapter 4 summarizes more detailed evaluation method of edges. In Chapter 5, the edges of variously oxidized carbon materials were evaluated.
