Advanced digital printing of electronics - Rapid development and pilot production of nanomaterials

Nanomaterials are the foundation of printed electronics 
The building blocks of any electronic circuit or sensor system are the materials. Nanomaterials increase electrical performance and add novel functionalities compared to already existing print processes, which are typically based on silver microflake materials. Furthermore, there is a push towards more sustainable and cost-effective materials. For these reasons, there is a clear need for rapid development as well as upscaling production of novel nanomaterials. 

Our service offerings


Rapid development services:

Danish Technological Institute can perform rapid development by combining artificial intelligence for Design of Experiments (DoE) and a fully automated small-scale flow and batch reactor technology. This combination both minimizes raw material usage and reduces development time to under three months.

Pilot production services:  

Once we have developed a particular nanomaterial, a challenge is to up-scale production to meet industrial demands. DTI has designed and built large scale solvothermal flow and batch reactor technologies, which can be tailored for a particular nanomaterial. The reactor technologies can be either semi or fully automated and can use on-line monitoring sensors with temperature, pressure, pH and even x-ray fluorescence technologies.

Nanomaterial characterization services:  

As part of the development and production services, DTI has a state-of-the-art characterization laboratory, with the following instrumentation:

  • Powder X-ray diffraction 
  • Electronic microscopy, SEM, STEM, EDX and FIB/SEM
  • BET and mercury intrusion
  • TGA
