Abstract

This work will aim to assess how the chemistry of nanoparticles produced via hydrothermal flow synthesis may be altered to tailor their electromagnetic properties at radio and microwave frequencies (1 MHz to 20 GHz) for electromagnetic control and absorption applications. By exploiting continuous hydrothermal flow synthesis’ ability to create samples at high throughput, large libraries of compounds will be synthesised, characterised and electromagnetically examined in order to better understand the relationship between the particles produced using this scalable synthesis technique and their electromagnetic properties. The result is to the knowledge of the author the most comprehensive materials discovery study of magnetic and dielectric nanoparticles with over 900 stoichiometries analysed. Whilst utilising a novel methodology, candidate materials which show improved characteristics in terms of impedance matching and loss behaviours across a range of interesting frequencies. Chapter 1 gives a background on electromagnetic interaction and potential useful applications for such interactions including a description of a number of different known EM (Electromagnetic) materials and devices. In Chapter 2, the experimental methods and materials that were undertaken in this body of work are outlined. Chapters 3 and 5 explore a large body of work concerning the high throughput materials discovery of EM nanoparticles. This involves the discussion of the physical sources of the observed EM behaviour observed in these particles and the analysis of mass data to help understand the structural property relationship of EM materials. In Chapter 4 and 6, the knowledge derived from the work undertaken in the previous chapters is used to progress the development of EM particles for certain desired properties they possess. Within this a number of different particle parameters are examined and their roles in effecting EM properties discussed. It is hoped that in this thesis, the progress in understanding of how synthetic adaptions alter EM particle behaviour made by this body of work is put across with clarity to the reader.
