Core modules:

Introduction to Materials Chemistry

This module begins with the electronic structure of atoms and uses this to introduce the chemistry of the periodic table. Crystal chemistry and crystal structures are then considered, starting with simple metals and then moving to ionic bonding and structures before considering glasses. The second half of the module introduces organic and polymer chemistry. Functional group chemistry and molecular shape are discussed using simple models of bonding. We emphasise the importance of macromolecules, together with the larger-scale shape of polymers. We discuss polymer synthesis and its relation to polymer properties some selected cases. This includes discussion of natural and biopolymers.
