通过同步小角X射线散射（SAXS），广泛的X射线散射（WAXD），使用几种启动的sampleds ander-Charmecopy和Cheme tamples and-Inteed-Inted-Interthe and-Intertics and and trame-Intertheats，研究了由天然橡胶（NR）中自然杂质（即蛋白质，磷脂，碳水化合物）诱导的多量表的微观结构。这些微观结构包括大骨料（尺寸小于50 m），定义明确的晶体（尺寸小于几小时）和胶束（尺寸小于10 m）。在未渗出的NR样品中，即使自然杂质的浓度相对较低，这些微观结构的分散也会显着影响机械性能
Multi-scaled microstructures induced by natural impurities (i.e., proteins, phospholipids, carbohydrates) in natural rubber (NR) were investigated by synchrotron small-angle X-ray scattering (SAXS), wide-angle X-ray diffraction (WAXD), and optical microscopy using several kinds of untreated and chemically treated un-vulcanized samples. These microstructures include large aggregates (size less than 50 m), well-defined crystals (size less than a few 10 m), and micelles (size much less than 10 m). In un-vulcanized NR samples, even though the concentrations of natural impurities are relatively low, the dispersion of these microstructures significantly affects the mechanical properties
