Yielding and structure under flow of gels and glasses of rod-like colloids
Abstract
In this dissertation we investigate the dynamics, phase behaviour, linear and nonlinearrheological response of suspensions of rod-like colloids with repulsive and attractive interactions.We use rheology in combination with various optical techniques including confocalmicroscopy to elucidate the role of microstructure in mechanical properties and flowbehaviour of rod suspensions. Micron sized silica rods suspended in various density andrefractive index matched solvents were used as the experimental model rod system. Thisdissertation is divided into mainly four parts. The first part discusses the role of confinementon the nonlinear rheological response of dilute suspension of attractive rods. Thesecond part compares the role of pre-shear history on the linear rheological response ofsemi-dilute suspensions of attractive silica sphere and rod suspensions. Third part investigatesthe yielding response of a dense suspension of repulsive silica rods. Fourth andlast part examines the relationsh ...
