Module summary

Having learnt about solids, liquids and gases, you are ready to learn some soft matter physics and liquid crystals. These are important states of matter that have intermediate order between the liquid and crystal solids. They are relevant to many aspects of science and technology, from display devices to biological. This module will provide you with the background physics behind the principal liquid crystal phases.

Objectives

- To provide a broad context of the properties of soft condensed matter
- To introduce the physics of liquid crystal and amphiphilic materials and liquid crystal devices
- To make clear the connections between the physical properties of liquid crystals and their applications.

Learning outcomes
On completion successful students will be able to:
- Understand the general concepts of soft matter physics and liquid crystals.
- Demonstrate analytical thinking in the choice of methods for characterising soft materials.
- Show creativity in solving problems, particularly the ability to relate material properties to device design.
- Apply physical methods learnt during the module to new problems in liquid crystal physics and devices, and soft matter systems more widely.
- Gain understanding in research methodologies applied to liquid crystal systems
- Become more aware of the commercial aspects of the LCD industry

Private study

Students will be given recommended reading at key points through the course. General recommended texts include:
R.A.L. Jones - Soft Condensed Matter, Oxford University Press, Oxford, 2002
I.W. Hamley - Introduction to Soft Matter, Wiley, Chichester, 2000
P. Collings, M. Hird - Introduction to Liquid Crystals
L. S. Hirst, Fundamentals of Soft Matter Science, CRC Press 2013
A key part of the module will be the assignment, and this will require wider detailed research and preparation.

Students will have to complete an online assessment at the end of the module. This will take place during the examinations period at the end of the semester and will be time bound. The assessment will not take 48 hours to complete, but students will have a 48 hour time period in which to complete it. Students must submit a reasonable attempt at all assessments for this module to pass this module.
