Summary on Grant Application Form |

Recent research has shown that macroscopic auxetic materials (i.e. those which expand laterally when stretched lengthwise due to having a negative Poisson's ratio) can have benefits as the barrier in separations processes (e.g. filtration). Specifically auxetic materials afford enhanced cleaning of fouled filters, effective pore size and shape tuneability, and pressure-drop variability as a result of the characteristic pore variation which occurs upon deformation of auxetic materials. It has also recently been shown that introducing defects into auxetic honeycombs by deleting honeycomb ribs leads to different effects on the mechanical properties of the honeycomb depending on the number and type of defects introduced. This proposal aims to extend this research down to the molecular level and will investigate the mechanical and separation properties of auxetic nanomaterials in pristine and defect (i.e. broken bonds, removal of atoms) forms. A suite of materials modelling methods will be employed, consisting of molecular modelling, Monte Carlo, finite element and analytical methods. Candidate molecular systems will be identified and will include idealised 2D and 3D molecular honeycombs to establish the modelling protocols and to perform validation with previously published data. More complex structures (organic and inorganic) will then be studied with potential in molecular sieve, ion exchange and biomedical (drug delivery) applications.
