We´ve been interested from some time in developing filters to purify water using graphene-made sponges. Once we uderstood the full extent of the coronavirus outbreak, one of the pressing issues was the lack of acces to quality respiratiors by the medical staff and the population in developing countries. It becomes a critical issue, if goverments want to prevent the spread of COVID-19. We thought we can used our filter to design a respiratior with a good quality filter made of a graphene-sponge.
What it does
It is a fIlter for mask respirators. It is a quality filter made of a sponge impregnated with a grahene ink.
How we built it
We used a commercial sponge impregnated with a graphene ink to fabricate a cheap and effictive filter to be inserted in a respirator. The ink was produced by a green chemical method from graphite powder.
Challenges we ran into
We can produce laboratory quantity samples. Scale up production can be a challenge. Access to reagents and equipment.
Accomplishments that we're proud of
It is possible to apply recent technological advances, using own capabilities, to solve problems in health and the environment.
What we learned
To develop materials for real-world applications is a big challenge. In particular, if a device is to be used by humans, extra care has to be taken in the design and quality of materials.
What's next for Graphene-sponge virus-grade filters for respirators
Create better and useful masks and filters.
