摘要： 本文报道用同步辐射二维小角X射线散射(2D\|SAXS)研究预氧化过程中张力对PAN纤维缺陷的影响.

Abstract: The effect of tension on the microvoids of polyacylonitrile(PAN)  thermal stabilized fibers was investigated by small angle X-ray scattering(SAXS) at Shanghai Synchrotron Radiation Facility(SSRF) at beamline BL16B. All SAXS patterns exhibit a very big anisotropy between the equator and meridian direction. The results indicate that the scattering bodies are elongated and oriented in direction of fiber axis. The quantitative parameters of orientation, length, diameter of the microvoids were obtained. The results show an obvious effect of tension to the microvoids' structure——a narrowing of the distribution of the microvoids misorientation and a more slender shape of microvoids, compared with the case without tension.

Key words: Polyacylonitrile(PAN) fiber, Stabilization, Small angle X-ray scattering(SAXS), Microvoid; , Tension
