Graphene and related 2-dimensional layered materials for emerging printable electronics applications supplied by Strem Chemicals UK working with DZP Technologies

Inter-digitated electrodes printed on stretchable TPU using ink F0280.

Our partner Dr Zlatka Stoeva is a managing director and a co-founder of DZP Technologies has been invited to speak at the 14th International conference on materials chemistry (MC14) the following is her abstract

Two dimensional (2D) materials are an exciting area of research and industrial innovation owing to their interesting and unusual properties, with almost unlimited number of commercial applications across different sectors. Graphene is the best known 2D material however hundreds of other 2D materials are reported in the academic literature, ranging from boron nitride to layered oxides and sulphides. Similarly, to graphene, these non-carbon 2D materials exist as monolayers of unusual properties. In contrast to graphene, they often have a tuneable bandgap and rich redox chemistry which enable their use in various electronic and photonic applications. The bandgap and hence the electronic properties of many 2D materials can be tuned through material design and processing.

This presentation will outline recent progress at DZP Technologies Ltd in the development of new manufacturing methods for the production of multi-litre quantities of 2D nanosheets. The 2D materials are then used to formulate functional inks comprising graphene and 2D transition metal dichalcogenides (TDM) such as molybdenum disulphide (MoS2) and tungsten disulphide (WS2). Results from advanced structural and chemical characterisation will be discussed and analysed, together with an overview of their performance in various sensor devices.

Importantly, the new production method and functional inks use aqueous chemistry throughout. This leads to environmentally friendly manufacture which eliminates the use of organic flammable and toxic solvents, offering significant economic and technical benefits.

The 2D printable inks can be used to produce electronic, photonic and optical devices of novel form factors and specifications. Examples which will be discussed include flexible strain and gas sensors which can be integrated into clothes, paper, or structural components such as electronic enclosures. These technologies create opportunities for new functionalities in smart phones, wearables, healthcare and connecting with the Internet of Things.
