sbiggs@andrew.cmu.eduDuring the Spring 2001 semester, Simon is teaching the following special topics course:
06-712 "Special Topics in Colloids and Dispersions"
Units: 12.0 Spring
MW 01:30 PM 02:50 PM
Location: TBDMy thoughts are revolving around a specialist course of "Polymers at Interfaces". I am thinking of building off of the information in Lynn Walker's course and the colloids course to give some lectures on the role of polymers in colloid science. I am thinking about topics such as (i) conformation at interfaces (effects of concentration, solvency, pH, salt etc. etc.), (ii) bridging and depletion flocculation (origins of forces, controlling parameters, kinetics of flocculation), (iii) steric stabilisation (thermodynamic considerations, solvency effects, intersegmental attractions etc.), (iv) direct measurements of polymers at interfaces (ellipsometry, small angle scattering (SANS, light, x-ray), reflectometry, surface forces (SFA, AFM, TIRM), imaging of adsorbed layers using AFM) and (v) Industrial uses of polymers in colloidal systems.
