Value Proposition


Vitor Abrantes
Founder & CEO

Vitor is a self-made entrepreneur with experience in Mechanical Engineering and Materials Engineering. Since 2013, Vitor has been driven by curiosity to develop the most sustainable and efficient production method for graphene materials. He received the “Business Idea Award 2014” from Dow Chemicals, placed 2nd on “EDP Innovation Award 2014” and won the “Henkel start-up award 2018” for his entrepreneurial spirit, technical innovation and management skills. He is a motivated and determined person that invested every asset he had to successfully prove that the concept technology and business model are the key to unlock graphene potential and its commercialization. Vitor has a track record on analysing and solving the most complex problems. The solutions implemented by him have saved more than one million euros in both CAPEX and OPEX since the foundation of Graphenest due to a bootstrap mindset and financial skills.

Bruno Figueiredo
Co-Founder, COO and Head of R&D

Bruno has a PhD in Chemical Engineering from the University of Aveiro (Portugal). He has been a graphene evangelist, researching graphene daily since 2014. He was elected as a member of the 2017 Industry class at Forbes 30 under 30 and gave a TED Talk about graphene and the new generation of materials driven by its use during that same year. His main interests are related with the synthesis and characterization of known and novel materials, as well as their commercial applications. He has a strong aptitude to set the direction and focus of his teammates, ensuring that they have the tools and resources to do their jobs. He connects researchers, suppliers, producers and buyers by implementing market-leading graphene-based technology and business.

Rui Silva
Co-Founder & CTO

Rui has an MSc degree in Chemical Engineering from the University of Aveiro (Portugal) and professional experience as a shift manager and quality/product technician, having been responsible for a multitude of tasks that ranged from industrial maintenance and laboratory management to internal/external audits. He is proficient in any tasks within a chemical/metrological laboratory and can also perform R&D with ease in various chemical processes areas. Rui’s expertise drives future technical development of Graphenest’s process unit. His professional experience in chemical production management and in quality control is an important guiding force towards improving the process’s physical and mechanical systems, as well as in characterizing the output.

Adriana Bernardes
R&D and Innovation

Adriana holds an MSc degree in Chemical Engineering and her dissertation was carried out at Graphenest, providing her with enhanced know-how about graphene production and its characterization (number of layers, aspect ratio, and impurities), particularly on the one developed by the company. Her knowledge in chemical processes also gives her the ability to develop new products and/or improve existing ones. She can also easily carry out any tasks in a chemical laboratory and is now the main responsible for the implementation of the nanomaterial on graphene-based products.

Patented Technology Process

Graphenest’s production system is based on a top-down approach, typically named liquid-phase exfoliation (LPE), where graphite sourced from 14 different locations is exfoliated on an entirely green aqueous solution (organic solvent-water). The organic solvent (along with temperature control) weakens the Van der Walls bonds between the graphite’s carbon atoms, priming it for physical/mechanical direct exfoliation. This process results in high-quality graphene nanoplatelets, which can be produced in a variety of grades (from mono-layer to multi-layer) and forms (dispersions or powders).

Both method and device for the production of graphene nanoplatelets have been patented and their use can be extended to the production of other graphene-like materials.
