摘要:

在这项工作中,我们提出的散射函数的共轭体组成的胶体粒子和自避免的聚合物链。该模型直接由两点关联函数导出,并考虑了体积效应。计算的散射函数的胶体和聚合物刚度的几何形状上的依赖性进行了研究。在现有的实验结果相比,我们的模型被发现能够描述的散射签名的胶体聚合物共轭物,并提供额外的构象信息。该模型明确阐明了共轭物的全局构象与其组成成分的微观结构之间的联系。

英文摘要:

In this work we present scattering functions of conjugates consisting of a colloid particle and a self-avoiding polymer chain. This model is directly derived from the two point correlation function with the inclusion of excluded volume effects. The dependence of the calculated scattering function on the geometric shapes of the colloid and polymer stiffness is investigated. In comparison to existing experimental results, our model is found to be able to describe the scattering signature of the colloid-polymer conjugates and provide additional conformational information. This model explicitly elucidates the link between the global conformation of a conjugate and the microstructure of its constituent components.
