Processable, customized

High performance few-layer graphenes without additives through innovative electrochemical exfoliation.

Our Products

Sixonia Tech‘s E-Graphenes are few-layer, large flake graphene materials that are functionalized and formulated to meet your processing requirements and tailored for perfect interaction with your desired matrix system.

Graphene is a promising material for different applications, particularly as an additive in polymers or ink formulations. Choosing the right type of graphene for each application is crucial to unleash its potential. At Sixonia Tech, we will identify the most suitable E-Graphene for your specific application and also develop the right material form and properties for perfect integration into your process and application.

No matter whether you are looking for a simple dispersion without surfactants, a formulated ink, a paste, a film, a polymer composite or something completely different, we are confident that we can develop the right material to meet your expectations.

Electrochemical exfoliation

Proprietary technology

based on research at the Max-Planck-Institute of Polymer Research Mainz and Dresden University of Technology

Customized solutions

tailorable for your needs via integration of functional groups and/or varying degrees of oxidation

Range of materials

various formulations such as aqueous and solvent-based dispersions and inks, as well as more viscous systems

Our Technology

Sixonia Tech’s core technology is based on the electrochemical exfoliation of graphite into micron-sized, few-layer graphenes.

The basic principle of electrochemical exfoliation is to introduce a slight electro-oxidation at the graphitic edges and subsequent delamination of graphitic raw materials in a suitable electrolyte. By varying the electrolyte composition and other process parameters, the degree of oxidation and the presence of different functional groups can be selectively controlled and the material can thus be tailored for different applications.

Our proprietary technology, originating in the works in the groups of Prof. Klaus Müllen and Prof. Xinliang Feng at the Max-Planck-Institute of Polymer Research Mainz and at Dresden University of Technology, allows us to produce graphene materials with unprecedented properties.

Sixonia Tech is a technology-driven startup company based in Germany, spun-out of the Chair for Molecular Functional Materials at Technical University of Dresden in 2017. Our core technology is the electrochemical production and functionalization of large-flake, few-layer graphene and its processing into various formulations. The underlying IP, developed at TU Dresden, is 100% owned by Sixonia Tech GmbH.

By providing good scalability and yield, low production costs and a good processability, our mission is to unleash the currently limited potential of graphene in various fields. We focus on the production and processing of electrochemically exfoliated graphene for different applications, in particular conductive inks and formulations, functional coatings and polymer composite materials. Our E-Graphene can be functionalized to meet your processing requirements and thus be tailored for perfect interaction with your desired matrix system. Compared to other “graphene” products, E-Graphenes show a superior combination of tailorable properties within a single material, such as large flake-size in the µm-range, low thickness in the range of 1-10 layers and good processability. For example, E-Graphenes can be functionalized to be dispersible in water without the need for surfactants, while still maintaining an intrinsic conductivity that is significantly higher than that of commonly used reduced graphene oxide (rGO) materials.


We’re always looking for curious and skilled people who believe that we can accomplish so much more together than apart.
