Many properties of materials are controlled by the surface characteristics, such as adhesion, friction, hydrophilicity, oleophilicity, antimicrobial activity, and static generation. These surface properties can be greatly altered by surface layers only 0.2-10 nm thick. My research group attempts to understand the physics and chemistry of these properties by controllably altering the outer 10 nm of high surface area materials, such as fibers and films. This also requires characterizing the surface on the nanometer scale. Our work involves new mechanisms of antimicrobial behavior, adhesion, electrostatic charge storage and dissipation, and hydrophilicity and oleophilicity.
