Many types of nanomaterials rely on the self-assembly process of their corresponding nanoparticles. Soft matter thin films are often used as templates to direct the assembly of the nanoparticles into desired arrangements. Commonly used strategies include template used for controlling deposition during solvent evaporation, and the use of the Langmuir-Blodgett method. In general, being able to control nanoparticle organisation plays a significant role in areas regarding tuning material characteristics, and in impacting electronic and optical properties.
It is therefore imperative that we get a better understanding of nanoparticle interactions with the film on a macromolecular but also a submicron level. Changes in parameters such as temperature and composition have been extensively studied, but they often include the presence of a substrate for the thin films, which, in turn, influences the overall assembly.
The aim of this project is to get a better understanding of the interactions between the nanoparticles and the film by not only studying how the nanoparticle assemble on the film, but also how the assembly can affect the film itself. To do that, we would need to compare systems of the same materials under different conditions.
This will be done by comparing studies of nanoparticle assembly behaviour on the surface of a) a templated film (the template presence of which will, obviously, influence the film structure and subsequent nanoparticle assembly), b) a free-standing thin film (i.e., without a template to influence the film structure), and c) the surface of a droplet of the same material as the films. To create self-standing films, a surfactant will be used in the mixes. Solutions will be aqueous-based in order to see the effects of evaporation of water from the 3 aforementioned configurations and the subsequent effect this has on the self-assembly of the nanoparticles. Simulations of the nanoparticle self-assembly and film/droplet changes during evaporation in the 3 aforementioned configurations will also allow for insight in the structures being formed.
Applications are welcomed from candidates who have recently completed Meng or BEng Engineering related degree or equivelant to MSc in an area of engineering or have relevant industrial experience, or equivelant .
