Abstract: Hybrid Films in Nanoscience and Bioscience Technologies
Hybrid films in emerging nanoscience and energy technologies operate near the envelope of their mechanical and adhesive properties with remarkably high levels of film stress. Reliability integrating new multi-functional hybrid films requires a new understanding of their mechanical properties and how they are related to underlying molecular structure. Similarly, some biological tissues like human skin are layered structures in which the biomechanical properties of component layers are crucial in understanding biophysical function, cosmetic “feel” and appearance, and processes of tissue regeneration like wound healing. Developing new treatments to reduce skin damage, to understand the role of environmental exposures, and to devise effective technologies to promote regeneration requires a new understanding of biomechanical function.
We will describe some of our research by selecting several examples involving hybrid materials in emerging nanoscience, energy and bioscience technologies. Specifically, we will discuss molecular design of multi-functional hybrids for resistance to moisture assisted cracking, the fracture behavior of materials in active layers and modules of photovoltaic devices exposed to hostile solar conditions, and finally, discuss the biomechanical function of human skin and the effects of treatments and technologies to reduce skin damage and promote regeneration.
