Figure 4: Multifunctionality of combining the thermal insulation, sound absorption, emulsion separation and electric conduction.
From: Ultralight nanofibre-assembled cellular aerogels with superelasticity and multifunctionality
(a) The thermal conductivities of the FIBER NFAs in air as a function of density. (b) Frequency dependence of the sound absorption coefficient of the FIBER NFAs (ρ=9.6 mg cm−3) and commercial 3M TAI2047 non-wovens. (c) Separation apparatus with the facile gravity-driven separation of water-in-oil emulsions using the FIBER NFAs (ρ=9.6 mg cm−3). (d) Photograph of the oil collection apparatus continuously collecting pure oil from water-in-oil emulsions. (e) Rt/R0 hysteresis of the CNFAs (ρ=5.1 mg cm−3) as a function of strain under a compressing and releasing cycle (ε=50%). The insets show that the brightness increases on compression of the CNFAs. (f) Rt/R0 of the CNFAs when repeatedly compressed (ε=50%) over 10 cycles.
