Preparation method and device for preparing microspheres through gas

Abstract

The invention provides a preparation method and device for preparing microspheres through gas. The preparation method comprises the steps of pushing protection gas into a preparation device, dropping solution into the preparation device and curing the added solution into spheres in solution in a receiving device to obtain target microspheres. The invention creatively provides the preparation method for preparing microspheres through gas, especially multi-surface incongruous microspheres; experiment equipment is simple and easy to assemble; utilized materials are all degradable materials with no pollution; the utilized method is simple and green and achieves quick preparation and uniform particle size; based on the advantages, all incongruous microspheres prepared through the method has wider potential application.

[0001] The invention belongs to the field of macromolecules, and in particular relates to a preparation method and device for preparing microspheres by using gas. Background technique

[0002] Janus is a god with two faces (two-faced god) in ancient Roman mythology. It is a term used to indicate that particles have two different characteristics at the same time. It was first proposed by Degennes in his Nobel Prize-winning speech in 1991. This term was later visualized to represent non-centrosymmetric particles with different properties, namely Janus Particles. In fact, this kind of asymmetric or non-uniform sphere is not completely asymmetric in shape and shape, but also includes the asymmetry of the chemical composition and performance of the two sides of the microsphere. The special structure and surface chemical composition of Janus microspheres have Anisotropy makes it unique in terms of physical and chemical properties. For example, Janus microspheres c...
