This chapter reviews characterization techniques with emphasis on their introduction and principle of operation for the experiments to achieve the goal of this thesis. Lights scattering techniques like dynamic light scattering, static light scattering, depolarized light scattering; deformation technique like rheology, microscopic technique such as transmission electron microscopy were used to probe the samples. Other techniques such as Raman spectroscopy, viscometry and tensiometry were also used. In addition, we also give brief accounts of materials such as clays and their characterization and solvents used in this thesis work.
