Effects of Shape and Size of Gold Nanoparticles on the Properties of Colloid and Nanocomposite
For more than a decade nanomaterials have attained huge attraction owing to the exceptionally different and excellent characteristics as compared to their bulk form. In the present research, we focus on understanding the properties and performance of nanocomposites in solid and liquid states. There are three major areas involved in this thesis research. Firstly, we will identify effective methods or techniques to evaluate nanomaterials. Conventional and non-conventional techniques will be implied. The second part is to study the interfacial reactions between nanoparticles (NPs) and fluid molecules. This is to obtain basic understanding of nanoparticles and their interactions with matrix materials. Thirdly, we will investigate the mechanical properties of nanocomposites. Experimental results showed that the mechanical properties of nanocomposites measured at macroscale exhibited differences when the shape and size of gold NPs were changed. The morphological characteristics of the material were shown effectively at the nanoscale based on the NPs' shape and size. The properties of NPs influenced the properties of gold colloid. Such changes were the result of the interfacial interaction of gold NPs and the host material.
