英文摘要： Self-assembly of amphiphilic copolymer is a route for the fabrication of novel functional nano-materials which has been the research hotspot. Expanding the new applications of the self-assemblied nano-materials is one of the greater challenge of self-assembly. This project integration of the free radical chain transfer polymerization, self-assembly, nano-dispersion and UV curing technology, exploring the synthesis and self-assembled micelles of linear and branched amphiphilic polymers with different topology structure and photoelectric activity which were used for dispersing carbon nanotubes (CNTs) and preparing complex colloid. Trying to grasp the effect of chain transfer monomer on the synthesis process and chain structure of branched polymer, and investigating the influence of the chain dimension and topology structure the amphiphilic polymer on the preparation process of self-assembed nanoparticles and the efficiency of photoelectric activity; Researching the effect of polymer structure on the surface activity of the assembly nanoparticles, optical properties and the capacity of dispersed carbon nanotubes; Exploring the interaction between the self-assembled nanoparticles and CNTs, and clarifying its mechanism and influencing factors; At the same time, expanding the application of multi-functional nanopartic
