Table 2. Short-Term Liquid Uptake (g Liquid/g Dry Foam)a.
sample | uptake after 1 s in n-heptane | uptake after 1 s in water | predicted uptake in cells (n-heptane) |
---|---|---|---|
WG | 2.6 | 1.8 | 3.2 |
WG/CNF | 2.6 | 2.3 | 3.8 |
WG/GEN | 2.4 | 2.3 | 4.2 |
WG/GEN/CNF | 4.2 | 2.4 | 4.5 |
Dry foam is in this case a foam equilibrated at 23 °C and 50% relative humidity (RH).
