This research examines reduction of microcracks in polyurea by addition of graphene and nanoclay on account of potential improvement in barrier properties. Graphene and nanoclay were added in different wt. fractions to polyurea followed by thin film preparation. The prepared thin film samples were characterized using scanning electron microscopy. Surface images before and after exposure to cryogenic temperature indicate that controlled addition of graphene and nanoclay to polyurea thin film can lead to a reduction in microcracking caused by thermal shocks.
