摘要

In summary, it is validated experimentally that nanoporous materials of non-hysteretic sorption isotherm curves can be employed to develop volume memory systems. Under the working pressure, as temperature changes, the effective wettability varies, and thus the liquid tends to either infiltrate into or defiltrate out of the nanopores, resulting in a thermally controllable actuation behavior. Due to the large specific surface area, the wettability variation is greatly amplified. Consequently, the energy density can be much higher than that of conventional smart solids. In addition, through a controlled-temperaturein filtration-defiltration experiment, it is validated that using electrolyte with temperature sensitive solubility can significantly increase the output energy density of nanoporous material functionalizedliquids, providing a promising way to enhance their performance. The infiltration pressure does not vary monotonically with the temperature; rather, there exists a critical temperature at which the infiltration pressure reaches the maximum value, which can be attributed to the competition between the thermocapillary effect and the cation exchange effect. The former mechanism is dominant in the high-temperature range and the latter is more pronounced in the low-temperature range.
