Description of field of research:
Reversible thermoplastic adhesives that can bond, de-bond and re-bond on-demand hold great potential in numerous applications where bonded structures need to be dissembled and reassembled rapidly based on operational demands. It has many useful applications such as emergency repairs, quick attachment and detachment of objects such as sensors, medical devices or prosthesis, the recycling and reuse of costly electronics components, "nail-less" construction materials, as well as modular system that can be readily be dissembled or selectively removed for an upgrade, repair, maintenance or reuse. Think 3M Post-it notes but even more useful!
As a Taste of Research student involved in this project, you will investigate how the performance of thermoplastic adhesives can be enhanced by the inclusion of magnetic particles and contactless magnetic induction heating. You will explore how the properties of the magnetic particles, the magnetic field strength and the type of thermoplastic affects the bonding, de-bonding and re-bonding properties. You will also explore how this technology can be applied to new applications. If you are interested in computational modelling, there is also the option of developing a multi-physic model in COMSOL that can be used to optimise the technology for specific applications.
The Taste of Research Scholar will work with a team of three academics and two postdoctoral researcher. You are welcome to contact Dr May Lim (by email at email@example.com or on Microsoft Team) about the research, the research team or for a tour of the laboratory in the new Science and Engineering Building.
As the Taste of Research Scholar involved in this project, you will gain new skills in magnetic materials characterisation and applications, the development of thermoplastic adhesive, as well as written and aural communication skills. The research will give us new insights into how key factors such as magnetic field strength and magnetic particle properties such as type, loading, and concentration affect the heating performance of the thermoplastic adhesive. This will lead to better design and optimisation of the thermoplastic adhesive, especially its bonding and debonding properties.
