ABSTRACT

The composite PAN fbers which incorporated with CNTs and Titania were prepared by mean of wet spinning. These fbers were then pre-oxidized with microwave heating in an air atmosphere. A combination of characterizations was carried out to study the impact of nanoparticles fllers on the properties of as-spun fbers and their performance during the microwave pre-oxidation. The addition of an equal amount of fllers made obvious changes in the chemical and crystalline structure, consequently improves the strength, and this could lower the capability to creep over a wide range of temperatures in the subsequent processes. FTIR and NMR analyses results of the pre-oxidized fbers exhibited clear changes in the PAN structure, where the dehydrogenation reaction and the degree of cyclization were investigated. Additional confrmation of the occur�rence of cyclization reaction was achieved by XRD and thermal analysis. According to the TGA results, the pre-oxidized CNT1 /Ti-PAN fbers exhibit greater thermal stability suggesting high carbon content and good quality could result in the dependent carbon fbers.
