Graphene and Carbon Nanotubes
Graphene-based materials are often used in sensors and wearable electronics for their flexibility and excellent conductivity. However, there are a few delicate processes to handle, which present several challenges.
Challenges:
- Graphene layers need to be as thin as possible for optimal flexibility and conductivity.
- Classical electronic depositing methods, including lithography and masking, require a longer preparation time, making them less accessible for low-cost electronics.
- Placing thin layers of graphene onto an object is a very delicate process that needs to be damage-free.
- Often, the deposition requires a special pattern or shape.
Your Advantages of Using Microdispensing at a Glance:
- Ultra-low volume handling to substrates of any type.
- No interaction between the dispenser unit and substrate prevents damage to the surface.
- Lines, curves, and other structures can be printed on-the-fly using the Autodrop system.
- Established in literature as a rapid prototyping process.
Example Applications of Inkjet-based Printing of Graphene and Carbon Nanotubes:
- InkJet-printed supercapacitor electrodes of graphene-carboxymethyl cellulose biocomposite Ink
- Graphene nanoplatlets and graphene oxide to form different functional electronic 3D structures
- Printing chitosan and carboxymethyl cellulose together with graphene structures into different electrodes.
- Printing conductive carbon nanotubes to from conductive structures.
- Print deformable and wearable carbon nanotube microwire-based sensors for monitoring of strain, pressure and torsion using single-walled carbon nanotubes.
- Printing of a polymere/CNT composite to form a gas sensor.
