Speaker: Reinhold H. Dauskardt

Protective hybrid films and coatings comprising inorganic and organic components tailored at molecular length scales are used in a wide range of emerging technologies. These range from protective transparent coatings for ophthalmic lenses, plastic windows and stretchable electronics, display and photovoltaic devices, membranes in fuel cells and batteries, dielectric layers in microelectronics and adhesive layers in high-performance laminates. In all case, characterizing and modeling thermomechanical reliability is paramount. I will describe our research by showcasing examples of molecular engineering to achieve organosilicate glass films and coatings with unprecedented combinations of mechanical and optoelectronic properties. We demonstrate some much unexpected thermomechanical properties that derive from the network connectivity and the role of precursor geometry. We probe the mechanical properties of polymer hybrid coatings in the extreme limits of molecular confinement where a stiff inorganic matrix phase confines the polymer chains to dimensions far smaller than their bulk radius of gyration.
Finally, I report on our internationally recognized open-air spray-plasma capabilities for versatile and low cost coating deposition on large and/or complex shapes in laboratory air and at low temperature. The generally solvent-free process further allows for the simultaneous functionalization of, and deposition on, substrates in a single step.
