![]() ![]() The invention relates to a switch type composite emulsifier containing a boric acid-based surfactant, which is prepared by dispersing inorganic nano particles on a boric acid-based surfaceAdding the composite emulsifier into oil phase or oil and water phases to obtain ultra-stable emulsion, and controlling pH and CO 2/N 2The concentration is used for changing the molecular structure of the boric acid group surfactant and the surface wettability of the inorganic nano particles, and the rapid conversion between 'emulsification' and 'demulsification' is realized, so that the boric acid group surfactant can be applied to occasions needing to keep the emulsion to be temporarily stable, has wide application prospects in various fields such as heterogeneous catalysis, emulsion polymerization and the like, has the characteristics of excellent sterilization, corrosion prevention, no toxicity, no pollution, easy biodegradation and the like, is combined with the conversion characteristic of the prepared emulsion, greatly reduces the environmental pollution caused by the surfactant, reduces the recovery difficulty, and accords with the development concept of green chemistry.
