Abstract:

Our aim in the previous studies was to design polymeric composites and blends that would heal defects that were present within the material. We considered three distinct approaches, which involved 1 Harnessing nanoparticles to heal cracks in layered composites 2 Using microcapules to deliver nanoparticles to damaged coatings 3 Exploiting photo-chemical reactions to create defect-free hierarchical structures. As we note below, our findings generated considerable interest in the scientific community. We are also initiating new studies on controlling crack propagation in brittle materials. Herein, we provide a brief description of our research in each of these areas.
