首先借助自洽场理论计算了树枝形高分子的径向密度分布函数,然后在二区域模型理论基础上,系统研究了树枝形高分子的“代数”、活性中心官能度、重复单元链节长度、有效相关系数和排除体积参数等对其特性黏数的影响.在理解树枝形高分子特性黏数与其微结构关系的基础上,从流体力学相互作用的角度,揭示了树枝形高分子的特性黏数不能反映其聚合度大小,而反映其平均携带溶剂能力的物理根源,从而为树枝形高分子功能的优化设计提供理论指导.
Firstly, the radial density distribution function of dendrimer was calculated by self-consistent field theory. Based on the theory of two-region model, the “Algebra” of dendrimer, the activity center functionality, Section length, effective correlation coefficient and exclusion volume parameter on the intrinsic viscosity of the dendrimer.On the basis of understanding the relationship between the intrinsic viscosity of dendrimer and its microstructure, from the perspective of hydrodynamic interaction, the dendritic polymer The intrinsic viscosity can not reflect the degree of its polymerization degree, but reflects its average physical ability to carry solvent, which will provide theoretical guidance for optimal design of dendrimer function.
