Dynamic light scattering studies on sterically stabilised polypyrrole colloids
We have examined a sterically stabilised polypyrrole colloid in aqueous acidic media using dynamic light scattering techniques. Our results confirm that this dispersion consists of non-aggregated primary particles with an average hydrodynamic particle diameter of 161 nm. A comparison of these results with our transmission electron microscopy data allows us to calculate an upper limit layer thickness of approximately 25 nm for the adsorbed poly(4-vinylpyridine-co-n-butyl methacrylate) steric stabiliser.
