摘　　要：无机纳米材料与高分子基质共混构成有机-无机复合材料,对其电学、光学和机械性能产生显著影响,因而受到广泛关注.为使其性能得到切实改善,需要使无机纳米材料在高分子基质中均匀分散.对其分散状态的检测传统方法是对材料进行超薄、连续切片后,The distribution of TiO2 particles as flatting agent in fine denier polyamide 6 monofilament was investigated via synchrotron radiation X-ray nano CT technique.2D and 3D reconstructed images of the polyamide 6 monofilament with different contents of TiO2 particles were obtained by treating the projection images with filter back projection algorithm and digital image processing methods.As the content of TiO2 particles increases,the agglomeration of TiO2 particles becomes more severe.As a result,agglomerated TiO2 particles whose diameter is around 800 nm were observed in the full dull polyamide 6 monofilament.The agglomeration of TiO2 particles is relevant to the decrease of the spinning stability in the manufacturing of full dull fine denier polyamide 6 fibers.
