Outline of Research at the Start

Patchy particles are of micrometre size and have patches on the surface. Such particles can assemble into complex structures with novel properties. In this research, we perform numerical simulation to investigate the relation of patchy particle design, assembled structures and properties.

Outline of Final Research Achievements

We have investigated the self-assembly of patchy particles on several aspects. (i) We have elucidate how the topological defects appear on the self-assembly of dipole-like patchy particle on a spherical surface. (ii) The mechanism of the growth and fluctuation of a dodecagonal quasicrystal assembled from patchy particles are revealed. (iii) We propose an inverse design algorithm so that for a given structure, the best type of patchy particle can be found out. (iv) Given the patchy particle and the desired structure, we propose to use reinforcement learning to learn the best control parameter during the self-assembly so that the desired structure is obtained fastest and most efficient.

Academic Significance and Societal Importance of the Research Achievements

The research shows that the self-assembly of nano- and colloidal particles is promising in the development of new materials. We have proposed simulation methods that help to find the best way to obtain desired structures.
