聚合物的研究
纳米尺度的表征可以帮助你找到答案。
在实验室中利用X射线散射,您可以:
- 测定自组装嵌段共聚物或液晶聚合物的相结构
- 揭示因注塑等加工过程产生的内部结构变化
- 在控制冷却过程中测试塑料的拉伸性能或结晶度
- 研究聚合物和复合薄膜的厚度和形貌
- 表征橡胶填料或聚合物胶体和胶束在分散体中的大小、形状和分布
用广角X射线散射法测定低水平结晶度
在采用集成的温度控制的动力学实验中,测量到的聚烯烃的结晶度低至0.3%。

SAXS/WAXS results help elucidate structure-funtion relationships in foams
Foams – gas trapped in solids or liquids – are common materials, found all around us. Liquid foams can be found in cosmetic formulations, home care products and food, whereas solid foams find use in […]
Polymer phase transformation
Simultaneous SAXS/WAXS measurements of a semi-crystalline polymer during thermal processing enables determination of route for phase transformation.
Silk fiber nanostructure investigation
SAXS/WAXS measurements enable the determination of the characteristic dimensions and the semi-crystalline structure of Bombyx mori cocoon silk fibers.
Determination of polymer crystallinity
The level of crystallinity of a polyolefin was determined during a kinetic experiment using the Xeuss SAXS/WAXS system in combination with an integrated temperature control stage, the Linkam HFSX350.

用X射线散射来进行聚合物的研究
“ In electron microscopy, you must prepare your sample by slicing and cutting the sample and therefore it gives no chance to study the properties in situ, during for example thermal treatment or mechanical testing . But with SAXS you can do it.”
