| titleOfInvention | Spherical polymer microcapsules by solute co-diffusion method (SCM) and their preparation method |
| abstract | The present invention relates to a method for producing a spherical polymer microsulfes using the solute co-diffusion method (business card of the present inventors), and more specifically, to disperse the polymer particles in an aqueous solution in which 0.1 to 1% by weight of a dispersion stabilizer is dissolved. Stage 1; 2 steps of preparing and adding a solvent emulsion containing a solute to the dispersion prepared in step 1 by using an emulsifier of 0.1 to 1% by weight; Three steps of swelling the solvent emulsion completely on the polymer particles; After the swelling is complete, there are four steps to remove only the solvent completely from the polymer / solute / solvent droplets.n n n The solute co-diffusion method proposed by the present invention is a new technique for preparing a micron-sized polymer capsule, and can not only arbitrarily adjust the trapping rate of the solute according to the degree of swelling, but also the amount of solvent used is much smaller than that of the conventional method. It is expected to be very usefully applied to the preparation of various polymer capsules because of its great advantage of ease. |
