Amphiphilic ternary molecular brush polymer and vermicular mono-molecular micelle constructed by same

The invention belongs to the field of self-assembly high molecular materials, and particularly relates to amphiphilic ternary molecular brush polymer and vermicular mono-molecular micelle constructed by the same. The structural general formula of the polymer is A-g-(B-r-C-r-D), wherein g refers to grafting, r refers to random copolymerization, A refers to polymer main chain, B refers to lipophilic high molecular side chain, C refers to high molecular side chain with photo-crosslinking structure, D refers to hydrophilic high molecular side chain, and the side chains B, C and D are randomly grafted on the main chain A. The vermicular mono-molecular micelle is obtained by slowly adding deionized water into an N, N-dimethyl formamide solution of the amphiphilic polymer dropwise, and removing N, N-dimethyl formanide through dialysis. The vermicular mono-molecular micelle prepared by the method is novel in structure, and shape and size of the micelle can be changed by changing grafting rate and molecular weight of precursor polymer, so that the vermicular mono-molecular micelle is extremely high in controllability.
