Project description
Graphene is known to have high specific surface area and excellent thermal/electrical conductivity, which sees itself in applications such as wearable electronic and energy storage. Recently a graphenic nano-materials called laser-induced graphene (LIG) has been widely investigated due to its easy, cost-effective and scalable synthesis. LIG is produced through a one-step laser treatment of commercial polyimide (PI) film substrate under an ambient atmosphere. However, the potential of LIG for use in technological applications is limited by its weak adherence on the PI substrates. In order to realise the full potential of LIG, it is necessary to preserve the LIG flakes’ connectivity and robustness. One way is to infuse it with other materials such as plastic and rubber. In this project we propose to embed LIG in fibre-reinforced composites as smart sensors for health monitoring. The excellent thermal and electrical conductivity of LIG offers an extremely versatile and wide-range sensing platform which can be exploited to provide information on the stress state or health conditions of a composite structure. The work will be primarily experimental, with the following work packages: (1) optimisation of the sensitivity of LIG’s properties to external environment, (2) integration of LIG in fibre-reinforced composites, and (3) testing and validation of the sensing system at the composite component level.
