Abstract: A colloidosome with a variable pore size and a preparation method thereof are provided. The preparation method includes the steps of modification of nanoparticles, preparation of amphiphilic nanoparticles, preparation of a colloidosome with a variable pore size and the like. Through specific setting of each step, the finally prepared colloidosome is stable and has a variable pore size, and a hydrophobic polymer chain in a cavity of the colloidosome has corresponding contraction and extension forms in different medium environments, such as water and oil, to block or expose pores, so as to meet application requirements for transmission in selective media.
