double layer

Twice the thickness

A double layer is two thicknesses of material stacked together: Use a double layer of cheesecloth for straining.

In electrochemistry, the term refers to the arrangement of charged particles that forms at the interface between an electrode and a liquid—positive ions on one side, negative on the other, creating two distinct layers of charge.
