| titleOfInvention | Preparation of polymer-liquid crystal microcapsules using swelling/phase separation (SPS) method |
| abstract | The present invention relates to a new technology for producing micron-sized spherical polymer-liquid crystal capsules using swelling / phase separation, and more specifically, one step of dispersing polymer particles in an aqueous solution in which 0.1 to 0.3% of a surfactant is dissolved. , 2 steps of finely emulsifying the reactive monomer including the liquid crystal in an aqueous solution containing 0.1 to 0.3% of an emulsifier, slowly swelling and swelling at a temperature of 25 to 30 ° C., after the swelling is completely finished, the polymer / liquid crystal / It consists of three steps that induce phase separation by polymerizing monomers in reactive monomer droplets. In this case, the polymer particles used include all polymer species having affinity with monomers regardless of linear or crosslinked structure. In this method, the emulsion emulsification, swelling process and stable polymerization process of the monomer including the liquid crystal are important factors for determining the final microcapsule form.n n n The swelling / phase separation method proposed by the present invention is a new technology for preparing a micron-sized polymer capsule, which can arbitrarily control the size of the liquid crystal in the particles according to the degree of swelling, and also controls the swelling through various particles. It has the advantage of being able to form a domain, and is expected to be a very useful technique for polymer dispersed liquid crystals. |
