Table 1.

Water vapor fluxes measured through VAGME devices and conventional GO films.

Membrane	Flux (60 °C) kg m−2 hr−1	Flux (80 °C) kg m−2 hr−1	Flux (100 °C)** kg m−2 hr−1
Conventional GO films	1.7–4.1* 9,27	(film cracking)	(film cracking)
VAGME (total area basis)	1.9 ± 0.1	5.6 ± 0.2	13 ± 2
VAGME (active area basis)	27 ± 1	79 ± 2	(1.8 ± 0.3) × 102
	Normalized flux (60 °C) kg m−2 hr−1 μm	Normalized flux (80 °C) kg m−2 hr−1 μm	Normalized flux (100 °C) kg m−2 hr−1 μm
VAGME (active area basis)	(5.4 ± 0.2) × 102	(1.6 ± 0.1) × 103	(3.5 ± 0.6) × 103

*The flux value from ref. ⁹ includes a calculated temperature correction based on vapor pressure driving force.

**The 100 °C data is time-dependent and the table entries are average fluxes over 12 h.
