Patterned Nanocomposite of Carbon Nanotube/Polymer

Motaragheb Jafarpour, Saeed January 2017 (has links)
Single walled carbon nanotubes (SWCNTs) are carbon based nanostructures with extraordinary electronical and mechanical properties. They are used in a wide range of applications, usually embedded in polymer as fillers to form polymer based nanocomposites, in order to affect the electronic behavior of the polymer matrix. However, as the nanotubes properties are directly dependent on their intrinsic structure, it is necessary to select specific nanotubes depending on the application. In addition, as randomly oriented CNTs (as Filler) embedded in the polymer matrix show lower electrical conductivity than expected, alignment of CNTs in the polymer matrix can help to improve the nanocomposite electrical conductivity. In this thesis, focus is placed on the electrical properties of the produced SWCNTs/Polymer nanocomposites. A simple patterning method called nanoimprint lithography is presented which allows the use of extremely low amounts of nanotubes in order to increase the electrical conductivity of isolated polymers such as polystyrene (PS). In addition, a flexible mold to pattern nanocomposite films, leading to the creation of conducting nanotube networks, resulting in Alignment of SWCNTs (from the bottom of the film to the top of the imprinted patterns) inside the polymer matrix. The project further investigated the effect of different imprint temperatures and pressures on the electrical conductivity of produced nanocomposite and a trend is found due to the variation of parameters. Finally an optimum imprint condition based on maximum achieved conductivity is suggested. During different steps of sample preparations, the samples were characterized by different microscopic and spectroscopic techniques such as Atomic Force Microscopy (AFM), optical microscopy, Spectroscopic Ellipsometer, electrical measurements and Raman spectroscopy.
