Adsorption From Solution

ABSTRACTA classic problem in polymer science is the preferential adsorption at a solid interface of one polymer species from a multi-component fluid mixture. Prototype systems for studying this selective adsorption process are solutions consisting of alkane molecules of two different lengths in the presence of a solid interface. Before neutron diffraction could be used to probe structural questions related to the selective adsorption process in such systems, a significant effort was required to develop methods for fabricating suitable samples. We describe techniques for preparing samples of long-alkane monolayers adsorbed on exfoliated graphite by adsorption from solution and by deposition from the vapor phase.

Chemically Selective

The first few atomic layers of a solid can form a barrier between its interior and an often hostile environment. Although adsorption at the vacuum-solid interface has been studied in great detail, little is known about adsorption at the liquid-solid interface. Adsorption at a liquid-solid interface is of intrinsic interest, and is of technological importance because it provides a way to coat a surface with monolayer or multilayer structures. A pinhole free monolayer (with a reasonable dielectric constant) could lead to the development of nanoscale capacitors with unique characteristics and lithographic resists that surpass the resolution of their conventional counterparts. Chemically selective adsorption is of particular interest because it can be used to passivate a surface from external modification or change the wear and the lubrication properties of a surface to reflect new and useful properties. Immunochemical adsorption could be used to fabricate novel molecular electronic devices or to construct small, “smart”, unobtrusive sensors with the potential to detect a wide variety of preselected species at the molecular level. These might include a particular carcinogen in the environment, a specific type of explosive, a chemical agent, a virus, or even a tumor in the human body.
