Biography

Molecular Characterization of Polymeric Surfaces

Dr. Hore obtained his Ph.D. in Chemistry at Queen’s University and in Physics at the Royal Military College. He then became a post-doctoral fellow at the University of Oregon, studying solvent and surfactant structure using a variety of computational and spectroscopic techniques. He joined the Chemistry Department at the University of Victoria in 2006, where he develops advanced optical methods and complementary theory to resolve fine structural details of molecules adsorbed at the solid-liquid interface, with special interest in influence of water on interfacial polymer structure. Through collaboration with ASAsoft (Canada), he has been studying silicone surfaces in response to chemical, electrical and biological stresses

Among the important properties of silicone is hydrophobicity but one of the challenges associated with contact angle measurement is that it a macroscopic quantity and does not provide molecular insight into the material property. Better understanding the behavior of a silicone insulation material in its environment requires better characterization methods due to the multitude of molecular interactions involved. This presentation describes developments in regard to fundamental surface characterization of insulator materials exposed to chemical and biological stresses. It also explains that there are changes in the silicone surface as a result of environmental exposures that in the early stage are not detectable by contact angle measurements or even surface probes.
