Interfaces in Complex Structures and Devices

Course aim

To provide the student with:

• An insight into the role of interfaces in determining the properties and performance of complex engineered products and devices
• Introduction to thermodynamics of interfaces 
• A knowledge of technologies for modifying interfaces
• Introduction to techniques used for studying interfaces
• Understanding of interfaces in composites materials and how these determine structural performance
• Understanding of role of interfaces in micro-devices and how to tailor to optimise device performance
• Understand the importance of interface science and surface chemistry in nanotechnology

Course content

• The significance of surfaces and surface chemistry in the interaction of materials (including nano- and biomaterials) with their environment and with each other.
• Surfaces and interfaces, surface tension and interfacial tension.
• Surface energy and its increasing significance as the size of materials decreases.
• Surface Thermodynamic, Helmholtz free energy, interfacial energy vs. tension interfacial, Zisman plots, contact angle and Young's equation. Hydrophobicity and hydrophilicity.
• Surfactants and surfactant aggregation. Surface dissociation, surface charge and zeta potential.
• Experimental methods to measure adsorption, contact angles, surface potential and surface forces.
• Techniques for surface analysis.
• Interfaces in Glass Fibre Reinforced Composites.
