Preparation And Characterization Of Polyimide/Organoclay Nanocomposites, Donavon Mark Delozier Jan 2002

Preparation And Characterization Of Polyimide/Organoclay Nanocomposites, Donavon Mark Delozier

Dissertations, Theses, and Masters Projects

The purpose of this research was to prepare nanocomposite materials comprised of exfoliated clay particles in a polyimide matrix. Poly(amide acid)/organoclay solutions and polyimide/organoclay films were prepared and the clay dispersion was characterized by visual inspection, XRD, and TEM. Mechanical measurements and certain thermal characterization measurements were also obtained. The research began by attempting to repeat the procedures set forth in the literature. Most of the polyimide/organoclay nanocomposites were being prepared by mixing prepared poly(amide acid) solutions with organoclay solutions. This simple mixing technology was used in the preparation of various polyimide/organoclay hybrid formulations. In-situ polymerization, which involved performing the …
