Table 2. Interfacial tensions of liquids and estimated surface stresses.

Liquids	γLV	γSV	γSL	ΥSV	ΥSL
Water	72	21*	40*	59	16
EG 40%	58	21*	28†	42	23

EG 40%, 40% ethylene glycol aqua solution; γ_LV, γ_SV and γ_SL are interfacial tensions (liquid–vapour (LV), solid–vapour (SV) and solid–liquid (SL) interfaces, respectively); Υ_SV and Υ_SL are the surface stresses of solid vapour and solid–liquid, respectively.

The properties were obtained from the literature41,42.

Each value is given in mN m⁻¹.
