摘要： Provided is a method for preparing an aqueous dispersion of metal nanoparticles having superior dispersibility and being sinterable at low temperature by modifying the surface of metal nanoparticles having hydrophobic groups with hydrophilic groups. Specifically, by treating the surface hydrophobic groups of the metal nanoparticles with a surface modification solution containing a surfactant and a wetting-dispersing agent, the treatment throughput can be improved about 10-fold and the particles can be monodispersed without agglomeration. Further, by using an antioxidant and a ligand removal agent in the solution, denaturation and oxidation of the particles can be prevented and the high-boiling-point hydrophobic ligands can be eliminated effectively. The hydrophilically treated metal nanoparticles may be dispersed in an aqueous-based solvent to prepare a metal ink sinterable at low temperature.

摘要： The present invention relates to a method of producing electroconductive electroless plating powder having excellent dispersibility and adherence, and, more particularly, to a method of producing electroconductive electroless plating powder having excellent dispersibility and adherence, using an electroless plating method of forming a metal plating layer on the surface of a base material made of resin powder in an electroless plating solution, wherein an ultrasonic treatment is performed at the time of forming the plating layer. The present invention has advantages in that an aggregation phenomenon, which is generated when the base material made of the resin powder is plated using an electroless plating method, does not occur and a plating reaction can be performed at low temperature, so that it is possible to obtain a compact plating layer and plating powder having improved uniformity and adherence with respect to resin powder. Further, the present invention, unlike the conventional technique, has advantages in that post-treatment processes are not performed and a plating reaction is performed at low temperature, so that the process operating cost is reduced and the processes are made simple.

摘要： Disclosed herein are acryl microbeads having a narrow particle size distribution and a method of preparing the same. In a method of preparing acryl microbeads through polymerization by stirring a polymerization composition containing vinyl acrylate monomers, an initiator and a dispersion stabilizer at a high speed to form microdroplets and increasing a reaction temperature to induce the polymerization reaction of the monomers within the microdroplets, a low molecular weight seed particle capable of absorbing vinyl acrylate monomers dissolved in a reaction medium outside the microdroplets is supplied at the time of the polymerization reaction, and thus the acryl microbeads have a narrow particle size distribution. The microbeads, which are almost completely free of fine and coarse particles and thus need no sorting process, which range in size from 1 to 50 μm, and which have a narrow particle size distribution can be prepared at a high yield without using a polymerization inhibitor. Exhibiting excellent physicochemical properties including color, transparency, etc., the microbeads can find a wide spectrum of applications in various industries including optical, cosmetic, and food industries.
