Table 1. Included in this table are the dielectric constant ϵ₀, the refractive index n, the measured contact angle θ and the non-retarded Hamaker constant H between liquid II and the following dielectric solids immersed in liquid I: TPP crystal, PET, PEN, PI, PVDF, PTFE, PE and calcium fluoride.

Material	ϵ ₀	n	θ (°)	H (10 ⁻²² J)
TPP crystal	2.96	1.72	CW	2.42
PET	3.76	1.58	CW	−1.12
PEN	3.4	1.64	67±5	0.42
PTFE	2.1	1.35	74±8	−6.36
PVDF	14.5	1.42	78±6	−6.20
PI	3.35	1.78	81±4	3.69
PE	2.3	1.54	NW	−1.67
Calcium fluoride	7.4	1.43	PW	1.50

Here CW, PEN, PW and NW stand for complete wetting, poly(ethylene naphthalate), partial wetting and non-wetting, respectively. The contact angle θ, which is measured at 220 K, is given in the form of the average ± its dispersion obtained from about 20 measurements of θ. Note that we could not estimate the contact angle for calcium fluoride substrate because of the limited sample geometry. We assign this substrate to PW at 220 K, as the nucleation frequency is higher for calcium fluoride than for a cover glass.
