1. A method for preparing thermosensitive nanocapsules, wherein the thermosensitive nanocapsules are prepared by forming a wall material from a free radical polymerization of two different N-alkyl acrylamide monomers;

  • the method comprises the following steps;

    (1) making an emulsifier aqueous solution by mixing an emulsifier and deionized water to form a water phase;

    (2) mixing and fully stirring a core material, the two different N-alkyl acrylamide monomers, a crosslinking agent, an initiator and a co-stabilizer to form an oil phase;

    (3) adding the water phase to the oil phase, forming microemulsion by shearing, and then forming a nanoemulsion via sonication; and

    (4) introducing nitrogen into the nanoemulsion and carrying out a reaction at 40-80°

    C., finally obtaining the thermosensitive nanocapsules;

    wherein the two N-alkyl acrylamide have a general formula of
