displayed in the Supporting Information, is due to a combination
of the crystalline nature of the neat TSIL and the increase in
viscosity upon CO2 complexation at the most available active
amine sites. The increased uptake at elevated temperatures,
displayed in Figure 10, coupled with the higher uptake displayed
by lower loaded [TMA][Tau] composites in Figures 5b
and 6, could indicate that the supported TSIL at the pore
openings may exhibit an increase in viscosity and/or swelling
upon the complexation of CO2 that induces diffusion limitations
of the CO2 molecules through the remaining supported
TSIL phase. Additionally, PXRD data, shown in Figure 12,
confirm the crystalline nature of the ionic liquid contained in
the [TMA][Tau] composites. These results are significant
