The researchers demonstrated a new process for 3D printing: graphene aerogels are finer

Graphene is a two-dimensional material with a unique properties, but to make full use of it, it must be reproduced in 3D.
good news, researchers at Virginia Tech have demonstrated their newly developed 3D-printed graphene aerogel solution with a much higher resolution than before.
, graphene only needs to appear in the form of "carbon atoms of a single layer of thickness"
the

. Although it has been applied in some cases, it is still a long way from actual input.
New technology allows graphene aerogels to be printed in 3D into larger shapes
simply stacking materials may reduce their strength and unique electrical, chemical, and optical properties, as there is not much difference between this time and ordinary graphite.
the porous form of a "graphene aerogel" and managed to fill the gap in 2D graphene with air. Other methods involve using lasers to forge graphene into 3D shapes, compress it into porous coral structures, foam 3D printing, or supported by carbon nanotubes.
graphene aerogel is extremely lightweight and can even be placed on strawberry silk without falling.
problem with graphene aerogels is that the way to shape them into the desired shape is not easy at all. In the past, it could be squeezed into thin wires up to 100 microns, but it was difficult to make further breakthroughs.
new virginia tech study is to improve that. Zheng Xiaoyu, author of the paper, said: '
technology, you can create very limited structures. However, without support, its fineness is quite limited, and it is not possible to obtain more free morphological factors".

what they did was design these graphene layers into whatever high-resolution shape you want.
this, the researchers prepared a hydrogel with graphene oxide and added cross-linking tablets. It is then separated by ultrasonic waves and combined with light-sensitive acrylic polymers.
then, the team was able to use time-projected micro stereolithing technology -- a very precise form of 3D printing that builds structures on an onlooker scale -- to create rigid long chains of polymers with graphene oxide inside.

and finally, the researchers placed the mixture in a furnace -- burning the polymer and leaving behind a graphene aerogel.
team says the technology can be used to make any three-dimensional shape graphene you want, with resolutions as fine as 10 microns, an order of magnitude higher than ever before.
