摘要： 用一维电子密度相关函数方法,分析了国产尼龙-1010不同拉伸比时的SAXS现象,由实验相关函数曲线可算得长周期(L),中间层厚(dtr),片晶层厚(dσ),非晶层厚(Aσ),平均片层厚(d),积分不变量(Q),比内表面Os以及(ηc-ηa)等数值及其变化规律。实验结果表明尼龙-1010的结晶结构是由结晶层、非晶层以及结晶-非品中间层三部分组成。

Abstract: The structures of Nylon-1010 with different draw ratio have been investigated by usingSmall-Angle X-ray Scattering(SAXS). It is shown that by using a simple geometrical cons-truction the following structure parameters can be directly derived from the correlation func-tion the long period(L), the thickness of the crystalamorphous interphase (dtr), the lamellarthickness(d), the "invariant"(Q), the specific inner surface (Os), and the electron densitydifference between the core of the crystallites and the amorphors matrix(ηc - ηa). The crystalline Nylon-1010 is probably consisted of three-phases: a crystalline layer, anamorphous layer and a transition zone between amorphous(Ao) and crystalline layer(do).

Key words: Nylon-1010, SAXS, one-dimensional electron density correlation function, crystal-amorphous interphase, long period
