EAG scientists are experts in surface analysis, including the various factors that affect surface chemistry and other surface-specific properties. When surface information is needed, we determine the most relevant analytical approach to obtain the best results. Our laboratories employ different surface analysis and surface characterization techniques to investigate and understand the issues associated with surface coverage, molecular orientation, functionalization, contamination, and surface segregation.
The chemistry of the upper monolayer of a surface can have a dramatic effect on surface wetting, biocompatibility, reactivity, and adhesion. For example, plasma processing and other gas-phase treatments are routinely used to alter the near-surface chemistry of polymer films prior to printing or adhesion steps. Similarly, organic silanes and thiol-terminated self-assembled monolayers can be applied from solution to modify the surface chemistry of glasses and metals.
EAG’s materials surface analysis laboratory solves issues with adhesion and bonding, questions regarding surface cleanliness and investigations regarding morphology and topography of materials’ surfaces.
