Seven different liquids having different polarity were used as probes for surface free energy calculations: Water, Diiodomethane, Thiodiglycol, Ethylene glycol, 1-Oktanol, Trichloromethane, and Dimethylformamide (see Table 3).
Within a very small set of samples, slight correlations were found to exist between diiodomethane and several of the household chemicals.
Moreover, double distilled water and diiodomethane attributed to polar and disperse parts of the sample were used to calculate surface tensions using Owens-Wendt equation [20].
Distilled water and diiodomethane (purity 99%, Alfa Aesar) were used for the measurement of contact angles.
The values of contact angles measured with water and diiodomethane on mainly dispersive solid surface do not change in time.

0[micro]1 droplets for a probe liquid triad (ultrapure water, diiodomethane, ethylene glycol) resting on the substrates of interest are produced.
In the hands of a skilled graduate student, it combines in a controlled manner with diiodomethane to generate a carbenoid reagent (EtZn[CH.
Diiodomethane and formamide (Aldrich) and distilled water were used as received for contact angle measurements.
Three different liquids were used for measuring the static contact angle: Milli Q water (with a bigger polar part), diiodomethane (with a bigger dispersive part), and formamide (with similar amounts of polar and dispersive parts).
