Single crystal polymer micelles with different length-diameter ratios and preparation method thereof

The invention belongs to the technical field of high polymer materials, and in particular, relates to single crystal polymer micelles with different length-diameter ratios and a preparation method thereof. The preparation method comprises the following steps: (1) synthesis of a block polymer; (2) synthesis of an ionic amphiphilic block copolymer containing a PCL crystal block; and (3) preparationof the single crystal polymer micelles: dissolving the ionic amphiphilic block copolymer in a good solvent, and dropwise adding ultrapure water at a preset speed to obtain an initial micelle solution;and dropwise adding a Hofmeist ion sequence solution, and stirring to obtain the single crystal polymer micelles with different length-diameter ratios. The preparation method disclosed by the invention is simple and convenient to operate, simple in process and mild in preparation condition, and can be used for preparing the micron-sized polymer micelles with the two-dimensional single crystal structure in a short time; th
