The present disclosure relates to the field of Pickering emulsifiers and emulsions, and specifically provides a Pickering emulsifier and a preparation method and application thereof. The Pickering emulsifier includes rhamnolipid-copper complex particles. The preparation method of the Pickering emulsifier includes the following steps: 1) preparing an aqueous solution of rhamnolipid, adjusting the pH value of the solution to be strongly alkaline, and making it completely deprotonated; 2) preparing a copper chloride solution: weighing the chloride Add copper to water and stir, 3) prepare rhamnolipid-copper complex particles: mix step 1) solution with step 2) solution, adjust pH, make it slightly weaker than step 1) in alkalinity, and particles separate out from the solution , centrifugation, washing, drying, that is. |
