Ink is an important material for printing. It can display text and patterns on the substrate by printing. However, you may rarely notice it, but it must be conceivable that most inks, especially color inks, are more or less toxic. This undoubtedly has an impact on human health or other aspects, and it is undesirable to everyone. Now, a new study will change this situation.
This research comes from ITMO University in St. Petersburg, Russia. They developed an ink based on colorless titanium dioxide colloids, which can be used on a variety of surfaces. Moreover, it produces different colors by changing the nanostructure.
Maybe you have a hard time understanding this principle, so let ’s take a more common example in life: for example, the wings of butterflies, we can often see colorful brilliance on them. Their reflected light interferes with each other in the way of light frequency, causing the surface It looks like many different colors.
The emergence of this new type of ink will change the existing printing form, making this work and similar items safer and making similar products look more different. And in addition, this process will also be used in the production of some cutting-edge equipment. Research papers have been published in the recent "ACSNano" magazine.
