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.

摘要翻译：本发明提供一种金属纳米粒子的水分散液的制备方法，该分散液具有良好的分散性，并且通过改性具有亲水基团的疏水基团的金属纳米粒子的表面而在低温下可烧结。具体而言，通过用含有表面活性剂和润湿分散剂的表面改性溶液处理金属纳米粒子的表面疏水基团，处理产量可以提高约10倍，并且粒子可以单分散而不聚集。此外，通过在溶液中使用抗氧化剂和配体去除剂，可以防止颗粒的变性和氧化，并且可以有效地消除高沸点疏水配体。亲水处理的金属纳米颗粒可以分散在水基溶剂中以制备可在低温下烧结的金属油墨。
