Polymer slides having hydrophobic small molecules
A plurality of polymer slides, each having a polymer part with a first polymer surface portion uncoated and a second surface portion coated with a metal. The first and second surface portions each have different surface coating properties and have respective first and second specified degrees of hydrophobicity which are different from each other. A hydrophobic small molecule is located in the polymer part of each polymer slide, and the hydrophobic small molecule and the polymer are essentially inert to one another. Adjacent polymer slides are arranged in a manner that the first polymer surface of one slide faces a metal coated second surface portion of another slide. The hydrophobic small molecule evaporates from said first polymer surface portion of the polymer part of one polymer slide onto the adjacent metal coated second surface portion of another polymer slide.
