Nanoengineering of Graphene-Based Devices

The main limitation to the widespread implementation of graphene is the challenge in manufacturing. This project will develop the chemical vapour deposition (CVD) route to producing graphene to a new level of capability, which can be routinely used to provide quantities of graphene for incorporation into devices, including fuel cells.
Aims and objectives
In the CVD graphene process, methane and hydrogen precursors are introduced at pressures of up to 1 atmosphere into a reactor heated to 800 – 1000 oC. More recently, a plasma enhanced derivative of the project (PECVD) has been developed, which can operate at significantly lower temperatures. Our vision is to take this technique forward to a new level of capability, such that it can be routinely used to provide practical quantities of graphene in a convenient and versatile form. We intend to modify the PECVD technique for use in a fluidised bed reactor (FBR), in which the process gases themselves are used to directly fluidise and coat nanoparticulates in a single-stage process. CVD processes are inherently flexible and scaleable surface engineering tools. Fluidised bed reactors are a highly efficient means of processing particulates. Thus, the aim of this project is to combine these two technologies together to develop a new manufacturing process with great capabilities for producing graphene nanomaterials.

We will initially demonstrate this process on plane surfaces and then develop the FBR based on previous experience in the project team. In the first instance we will seek to deposit graphene directly onto anatase titania nanoparticles to enhance their photocatalytic performance. This will give a tangible demonstration of our vision and a springboard for the further development and commercialisation of a new manufacturing process.
The successful development of FBR graphene doping of nanoparticles will provide a means of integrating graphene more readily into devices. In particular, we will seek to incorporate the graphene coated nanoparticles into inks and ribbons to allow this material to be screen-printed and 3D printed. This will allow the exploitation of graphene’s unique properties in many other applications including sensors, composites, printed electronics, organic light emitting diodes, as use as separation materials, electrochemical energy storage/generation, stealth materials, smart textiles and many more.

This multi-disciplinary project has a number of well-defined objectives:

* developing the CVD graphene process;
* transferring this process to a FBR;
*characterisation of the graphene doped nanoparticles;
* incorporation of nanoparticles into inks and ribbons, which can be used to print devices/products;
* optimisation of device/product performance;
* developing an engineering solution for continuous processing.


This project will dovetail with existing graphene and thin film research projects currently underway and planned in the Surface Engineering and Advanced Materials Research Group and will expand our portfolio of techniques and applications. The group is well equipped with deposition and characterization facilities and has the expertise to design and modify equipment as required. The supervisory team have national and international industrial and academic collaborators in this field that are willing to contribute materials or test devices, and they will be brought in to support this project.
Specific requirements of the project
The candidate is required to have a background in engineering or a related scientific discipline and a keen interest in material science. Experience of thin film deposition (CVD or PVD) and characterisation (e.g. SEM, EDX, XRD, Raman) techniques will also be a distinct advantage. The candidate will need to demonstrate adaptability due to the multi-disciplinary nature of the work, and the capacity to carry out experimental work safely, and with precision. An ability to work as part of a diverse team, to meet deadlines and produce reports and presentations of a high standard to a range of audiences is essential. Applicants will require initiative, self-motivation, good communication skills, and the ability to critically evaluate their work. A willingness and ability to travel is an advantage, as the project may involve a short period of work at collaborating groups.

The successful candidate would be expected to start as soon as possible.
