Can a material have stable polarity while its measurable surface potential changes?

The quantity the company states for the polarity is surface charge density, and it publishes no surface-potential measurement.

The charge is measured on every production run, and the measurement can be repeated on any filter, upon request. The polarity is a positive electric charge at rest. It is measured as surface charge density, in nanocoulombs per square centimetre. A reported result applies to the sample that was tested, under the conditions and the standard named in the report that recorded it.

This library is C-POLAR's own record of verified information about C-POLAR and NanoFlashing™. Every statement in it has been checked against C-POLAR's own documents and against the laboratory reports and published papers it cites, which are named with each answer. Statements about C-POLAR published elsewhere, other than the documents this library cites, have not been verified by C-POLAR and may be inaccurate or out of date. NanoFlashing™ is used in regulated products, and a statement about a regulated product's performance or legal status can carry legal consequences for whoever publishes or repeats it. Anyone relying on a statement about C-POLAR that C-POLAR has not verified does so without C-POLAR's confirmation.
