Abstract |
In this dissertation we investigate the dynamics, phase behaviour, linear and nonlinear
rheological response of suspensions of rod-like colloids with repulsive and attractive interactions.
We use rheology in combination with various optical techniques including confocal
microscopy to elucidate the role of microstructure in mechanical properties and flow
behaviour of rod suspensions. Micron sized silica rods suspended in various density and
refractive index matched solvents were used as the experimental model rod system. This
dissertation is divided into mainly four parts. The first part discusses the role of confinement
on the nonlinear rheological response of dilute suspension of attractive rods. The
second part compares the role of pre-shear history on the linear rheological response of
semi-dilute suspensions of attractive silica sphere and rod suspensions. Third part investigates
the yielding response of a dense suspension of repulsive silica rods. Fourth and
last part examines the relationship between particle orientation and shear thickening in
dense silica rod suspension.
