| 英文摘要 | In order to physically elucidates the anomalous intrinsic viscosity of dendrimers, first, the radial segmental density profile of dendrimers is calculated by the self-consistent mean field method. Secondly, based on the two-zone model proposed, the intrinsic viscosity as a function of generation of dendrimers with the following parameters, including the number of generations, the functionality of the core, the length of spacer, the effective coefficient of correlation and the excluded volume is systematically investigated. Thirdly, the origin of dendrimers' anomalous intrinsic viscosity is elucidated in the microscopic scale, namely the competition of the number fraction between the two kinds of monomers without the capability of dragging solvent, which is caused by the increase of volume of the core and the back-folding ability caused by entropy effect. Finally, it is physically elucidated that the nature of the intrinsic viscosity is the reflection of the ability per monomer of dendrimer to averagely drag solvent molecules alone rather than the reflection of the degree of polymerization. This research will be benefit for the optimum design of dendrimer materials in the corresponding application areas. |
