AIMS

Introduction to soft condensed matter: range of applications and products including foods, cosmetics, pharmaceuticals, ceramics, suspensions, minerals and detergents. The course covers the fundamental structure-function and material properties of these complex systems.

INDICATIVE CONTENT

The colloidal domain: brownian motion and the Stokes-Einstein equation. Suspension viscosity.
Interparticle forces: dispersion forces, electrostatic forces (Poisson-Boltzmann), double layer theory and solvation forces. The role of surface forces in colloidal stability. Electrokinetic characterization of nano-particles and the relationship to colloidal stability and suspension rheology. Suspension rheology, measurement, viscoelasticity and the colloidal state. Polymer physics. Polymers as random walks, ideal and real chains scaling concepts and the size of the random walk. Entropy and Elasticity, the Hookean spring. Viscoelastic behaviour of polymer solutions and melts. Gels, sols and gelation including the concept of percolation. The theory of rubber elasticity. Adsorption of polymers to surfaces. Surfactants and self assembly. Micelles, vesicles and hexagonal phases. Aggregation numbers and packing parameters. Lipid bilayers. A review of several papers in biotechnology and nanotechnology.

INTENDED LEARNING OUTCOMES (ILO)

On completion of this subject the student is expected to:

1. Describe and analyse the flow behaviour of particulate materials and the influence of surface chemistry, additives and processing history on the behaviour of fine solid and liquid particle slurries
2. Apply the physical concepts to product formulation with required material attributes
3. Apply the physical concepts to processes in the minerals, ceramics, pigment, food and pharmaceuticals industries
4. Apply these concepts to the manufacture and characteristics of ceramic, cemented and geopolymerised materials and a range of plastic and filled plastic materials.

• One written 3-hour end-of-semester examination. Intended Learning Outcomes (ILOs) 1 to 4 are addressed in the exam (80%)
• One assignment of at least 3000 words (not including appendices and diagrams and tables). Time commitment of 25-30 hours. Due in the second half of the semester. Intended Learning Outcomes (ILOs) 1 to 4 are addressed in this assignment (20%).

Hurdle requirement: A grade of greater than 50% in the exam is required to pass the subject.
