Preparation of polybenzoxazine-derived partially ordered carbon

Abstract

Partially ordered carbon have been widely studied and used in various applications such as gas separation, catalyst supports, and electrode materials. They have been conventionally prepared by pyrolysis and physical or chemical activation of organic precursors such as polymers, in which the pore size and pore structure, can be controlled at a high temperature in inert atmosphere. In this study, the solventless process was used to prepare polybenzoxazine precursor, which was synthesized from formaldehyde, phenol and aromatic diamine to produce nanocarbon with high chair yield. The effects of the pyrolysis temperatures on the microstructure of the obtained partially ordered carbon were investigated. The change in the chemical structure of polybenzoxazine was examined by FTIR and TGA was used to investigate thermal properties. The physical properties were examined by SAA. In addition, XRD was used to demonstrate the characteristics of d spacing in partially ordered carbon. The electrical property of partially ordered carbon was observed at room temperature by an electrometer with two-point probe.
