CHEM61082 Soft Matter Chemistry

 

Unit code: CHEM61082
Credit Rating: 15
Unit level: Level 6
Teaching period(s): Semester two

Aims

To provide the students with a detailed understanding of surface chemistry and modern polymer chemistry. Students will learn about the colloidal state, electrified interfaces and electrochemical energy storage. They will also learn about the relationship between polymer structure and properties. Students will develop an appreciation of the importance of polymer chemistry, electrochemistry and surface chemistry in a range of applications.

Overview

Surfaces & Interfaces - Prof Andrew Horn

  • Basic structure and properties of solid surfaces (solid structures, unit cells, Miller indices, surfaces of compounds and surface coordination numbers)
  • Surface reactivity (electronic structure of surfaces, bonding to surfaces, physisorption and chemisorption, mechanisms of surface reactions, thermodynamics at surfaces)
  • Surface kinetics (rates of adsorption and desorption, equilibrium coverage, simple isotherms, competing reactions)
  • Liquid surfaces: surface tension, adsorption & surface activity
  • Gibbs adsorption isotherm & surface pressure

Colloids & Electrochemistry - Prof Robert Dryfe

  • Micelles
  • Colloids examples & stabilisation
  • DLVO & Gouy-Chapman theories
  • The double layer at electrode surfaces
  • Dynamic electrochemistry and electrode kinetics
  • Energy conversion & storage fuel cells, supercapacitors, batteries.

Physical properties of Polymers - Prof Peter Budd

  • History of polymers; natural polymers; synthetic polymers.
  • Physical states of polymers; glass transition temperature; rubber elasticity; high free volume glassy polymers.
  • Crystalline melting point; crystal structure; polymer stereochemistry; polymer single crystals; morphology of semi-crystalline polymers.
  • Distributions of molar mass; average molar masses.
  • Gel permeation chromatography (GPC).
  • Dilute solution viscometry; Mark-Houwink relationship; universal calibration for GPC.
  • Radical chain polymerization: dependence of rate of polymerization and of degree of polymerization on initiator concentration.
