The invention provides a method for preparing liquid marbles. The method is as follows: dissolving sodium acetate in ultrapure water, shaking and dissolving to obtain a sodium acetate solution, adding it dropwise on a hydrophobic substrate, and then heating it at a temperature of 20°C to Evaporate and crystallize at 30°C to obtain liquid marbles. The present invention can be carried out at room temperature with a temperature of 20°C to 30°C, the preparation conditions are loose, and no complicated technical and equipment support is required; and the prepared liquid marble with "solid outside and liquid inside" has a dense solid crystal shell on the outside The structure has good encapsulation performance, which can effectively prevent the evaporation and volatilization of the liquid inside the liquid marble.
Description
A kind of preparation method of liquid marble technical field The invention belongs to liquid marble preparation technical field, be specifically related to a kind of preparation method of liquid marble. Background technique [0002] Nature has created many miraculous natural phenomena. After the rain, the country road covered with dust falls to the ground. The raindrops do not shatter immediately, but form free-rolling balls under the dust The water evaporates and shriveled and cracked. Inspired by this, after the liquid marble was proposed as a new concept, it was obtained by researchers. staff's attention. As a new research direction, liquid marbles have great application potential and can replace capsules in medicines The shell is used in the medical field, and even in the military field, it can be used for the manufacture of liquid bombs. The liquid marble in the traditional sense is formed by wrapping a layer of micron or nanometer superhydrophobic particles ...
