In this work, PAN-based carbon fiber papers (CFPs) were prepared with various weight of oxidized single walled-carbon nanotubes. The electric properties, mechanical properties, surface energy and porosity of the resulting CFPs were investigated. The influences of the oxidized single wall carbon nano tubes contents on the electric and mechanical properties were also examined. The morphology of CFPs was observed using scanning electron microscopy and X-ray diffraction. The electric properties of the prepared CFPs were characterized by four-probe point method. The surface free energy was investigated using contact angle measurement of three liquid droplets. The porosity of prepared CPFs was examined by mercury porosimetry. The results indicate that amounts of oxidized single wall carbon nanotubes affect the electric and mechanical properties, and surface free energy of carbon fiber papers. |
