| 摘 要： | Polyacrylonitrile preoxided fibre PANOF is an intermediate in carbon fibre preparation. Thequality of PANOF is closely related to the property and structure of carbon fibre. In this paper, thermal mechanical analysis(TMA), thermogravimetric analysis(TGA), swell-ing differential scanning calorimetry(SDSC)and X-ray photoelectron spectroscopy(XPS)wereused to study the increase in tenacity of PANOF from the precursor treated with cuprous salt It has been discovered that the cuprous salt reacts strongly with the uncyclized CN of PANOF,resulting in an increase in the tenacity of PANOF by 30%. The results shwo that the cause of thistenacity improvement is the formation of coordinated complex. Cu~+is the central ion, and PANOFthe ligand. It is due to the coordinate bond that the network structure is formed from uncyclizedCN of PANOF. Therefore the tenacity of PANOF is remarkably increased.
