Direct-writing of viscoelastic nanoparticle colloids for three-dimensional solid freeforming

已经使用胶体纳米颗粒墨水研究了纳米颗粒的简单和灵活的组装图案化。通过控制分散相的表面力，纳米粒子墨水被物理凝胶化。凝胶化油墨通过其沉积实现逐层组装，从而可以直接制造三维结构。本研究主要制备含有陶瓷或金属等功能性无机纳米粒子的油墨。

Simple and flexible assembly patterning of nanoparticles has been investigated using colloidal nanoparticle inks. The nanoparticle inks were physically gelled by controlling surface forces of dispersing phases. The gelled inks enabled layer-by-layer assembly through their deposition, and thereby three-dimensional structures can be directly fabricated. In this study, inks containing functional inorganic nanoparticles such as ceramics or metals were mainly prepared.
