Description
This course introduces students to colloid and interface science. Key surface chemistry concepts are introduced, including the role of surface energy and adsorption of molecules at phase boundaries or interfaces. In introducing colloidal materials, emphasis is placed on the methods of their preparation and structure-property relationships. Dissolved polymers are ubiquitous in everyday formulations and thus the behaviour of polymers in solution is investigated. The self-assembly of amphiphiles into soft materials including micelles, liquid crystals and microemulsions is examined, and the relationship between these structures and formulations in which they are used is explained. The laboratory component provides training in techniques which are specific to the preparation, characterisation and simulation of dilute and concentrated surfactant and polymer solutions, and colloidal dispersions. Throughout the course, the relationship between the structure and properties of the materials and their performance in household, environmental and industrial applications will be highlighted.

Learning outcomes
On successful completion of the course students will be able to:
1. Relate the structure and properties of surface active and polymer molecules, and colloidal materials to their performance and intended applications;
2. Describe the different approaches to the classification and preparation of colloidal materials and soft matter;
3. Describe the use of surface-active, soft matter and colloidal materials in household, industrial and environmental applications;
4. Demonstrate competence in the use of various procedures and instruments for the synthesis and/or characterisation of surface-active molecules, soft matter and colloidal materials;
5. Apply the scientific process in the conduct and reporting of experimental investigation;
6. Demonstrate an awareness of the safety responsibilities involved in working with chemicals and hazardous substances.
