The classical model of continuous helix-twist lamellae versus a novel corrugate-grating assembly in accounting for long-debated issues of periodic optical banding in poly(ethylene adipate) (PEA) polymer spherulites is critically assessed, by comparing and checking against a series of scientific evidence based on experimental data of scanning electron microscopy (SEM), ultrathin microbeam small-angle & wide-angle X-ray scattering (SAXS/WAXD), and optical microscopy. Analyses show that grating-structured model fits perfectly with all results. The novel proposition of grating-structured lamellae with a crossbar pitch fits perfectly with the experimental optical band spacing, and the interior morphology dissection is fully supported by the literature-reported microbeam X-ray data.

形态分析证明聚己二酸乙二醇酯的带状球晶中的波纹状格栅薄片组装

通过比较和对照一系列因素,严格评估了连续螺旋扭曲薄片与新型波纹光栅组件的经典模型,该模型解决了聚己二酸乙二醇酯(PEA)聚合物球晶中长期争论的周期性光学带问题。基于扫描电子显微镜(SEM),超薄微束小角度和广角X射线散射(SAXS / WAXD)和光学显微镜的实验数据的科学证据。分析表明,光栅结构模型完全符合所有结果。具有横杆间距的光栅结构薄片的新主张与实验光学带间距完全吻合,并且文献报道的微束X射线数据完全支持内部形态解剖。
