Humidity driven intelligent clothes and a preparation method thereof. The present invention belongs to the field of functional polymer materials, and especially relates to humidity driven intelligent clothes and a preparation method thereof. The present invention aims at solving the problems that in the prior art, intelligent clothes are difficult to prepare and cannot directly washed by water, electronic components are required to be additionally added, and cost is high. The intelligent clothes comprise two structures, one is a structure having windows which can be opened and closed, and the other is a structure having an arched support structure. The two structures can adjust human body surface temperature through relative humidity, for the intelligent clothes having the opened and closed porous structure, temperature is adjusted by controlling holes to open and close through the human body generating perspiration, and for the intelligent clothes having the arched support structure, the temperature is controlled by automatically adjusting thicknesses of the clothes through relative humidity generated by the perspiration. The humidity response intelligent clothes have stable moisture absorption performance, the temperature can be automatically adjusted under different relative humidity conditions, and the reaction process is rapid with only a few seconds or tens of seconds.
