Polyimides are attractive polymers because of valued
intrinsic properties such as high thermal stability and good
solvent resistance. At the same time, much effort is put
into modifying polyimides to introduce different properties.
This thesis describes a study where polyimides were modified
with soluble metal compounds in an effort to create microcomposite
films in which the location of the composite
structure was controlled; namely at the film interfaces.
Two different modification techniques were used in this
study, in-situ chemical generation and infusion deposition.
Results indicate that infusion deposition was successful in
producing a gradient microcomposite structure in polyimide
films when silver(I)nitrate was the metal dopant. Analysis
revealed that formation of the microcomposite structure
depends upon the glass transition temperature and precure
temperature of the polyimide film being modified.
