Polyacrylonitrile (PAN)-based Carbon Fibers

The effects of the microstructure evolution of amorphous carbon on the tensile behavior of polyacrylonitrile (PAN)-based carbon fibers were investigated. The microstructure as a function of heat treatment temperature was characterized by means of XRD, HRTEM and Raman spectra. It is found that the amorphous carbon content decreases with increasing heat treatment temperature and that the ...

Carbon fibers have high surface areas and rich functionalities for interacting with ions, molecules, and particles. However, the control over their porosity remains challenging. Conventional syntheses rely on blending polyacrylonitrile with sacial additives, which macrophase-separate and result in poorly controlled pores after pyrolysis.
