Course Description

In this course, students will learn fundamental phenomena observed in colloidal dispersions and related characterization techniques.


Attendance, reports, and exams.

Course Goals

To understand the basic phenomena in colloidal dispersions, including particle charging, interactions, and phase behaviors.

Course Topics

Theme Class number of times Description
Colloidal Dispersions 1 The definition of colloidal dispersions and their wide applications will be described.
Particle Charges and Interpartticle potentials in Liquids 5 In this theme, following topics will be explained: the formation of electric double layer, the derivation of electric potential by solving the Poisson-Boltzmann equation, and the interaction between two charged surfaces.
Characterization of Colloidal Dispersions 2 In this theme, characterization techniques of colloidal particles will be introduced, including dynamic light scattering, the measurements of electrophoretic mobility and surface forces.
Equilibrium Phase Behavior 3 Colloidal suspensions show an order-disorder transition, which is analogous to the solid-liquid transition of molecular systems. This theme will deal with colloidal crystals formed through the order-disorder phase transition, and the formation process and their optical properties will be discussed.


Reference materials will be distributed during the lectures if needed.
