UCalgary Researchers Create 3D-printed Materials With Liquids

The team added nanoparticles to water and chemical compounds, or surfactants molecules, to oil. One of the researchers, Dr. Hossein Hejazi explains, “By injecting this water into the oil, the interface between the oil and water spontaneously turns into emulsion, forming an interfacial skin made of many tiny water droplets that are sticking together.”

This creates 3D tube-like structures in the oil, which can be injected with other materials, and this liquid-in-liquid process could enable many potential uses including energy storage, microreactors, and for creating biomimetic materials like tissues and polymers.
