Nanoparticle Inks - Nanotechnology

What are Nanoparticle Inks?

Nanoparticle inks are formulations containing nanoparticles suspended in a liquid medium that can be used for printing and coating applications. These inks leverage the unique properties of nanoparticles, such as their small size, large surface area, and tunable physical and chemical properties, to achieve functionalities that are not possible with conventional inks.

How are Nanoparticle Inks Made?

Nanoparticle inks are typically synthesized through a multi-step process that involves the synthesis of nanoparticles, stabilization in a liquid medium, and formulation into an ink. Common methods for synthesizing nanoparticles include chemical reduction, sol-gel processes, and thermal decomposition. Stabilizing agents, such as surfactants or polymers, are often added to prevent aggregation and ensure a stable dispersion.
