Abstract
Lecithin is coated onto the surface of plastics such as polystyrene and polyethylene to enhance the wettability of aqueous liquids to the plastic. In one application, plastic test wells are coated with lecithin to enhance the ability of liquids placed into a well with sloping sides to flow in a regular manner into a well with vertical sides. The lecithin is applied to the plastic by dissolving the lecithin in an organic solvent such as heptane, coating the solution onto the plastic surface, and evaporating the solvent.
