Which probe liquids are assumed?

This version uses water and diiodomethane default component values.

What components are reported?

The calculator reports dispersive, polar, and total surface energy.

Can rough surfaces bias this?

Yes. Roughness, swelling, absorption, and contamination can bias contact-angle-based estimates.
