摘要： The present invention achieves a moisture absorbing material which enables efficient dehumidification without supercooling or large heat quantity; and a dehumidifier in which the moisture absorbing material is used. The moisture absorbing material can be a dried product of a polymer gel in which an interpenetrating polymer network structure or a semi-interpenetrating polymer network structure is formed by (a) a stimuli-responsive polymer whose affinity with water changes reversibly in response to an external stimulus and (b) a hydrophilic polymer.

摘要： Provided is a dehumidification apparatus with good energy efficiency. A moisture absorbing material (polymeric moisture absorbing material 24), which absorbs moisture and swells at a temperature not higher than a predetermined temperature sensitive point, while shrinking and releasing condensed water at a temperature higher than the temperature sensitive point as a result of phase transition, is formed so as to be divided into a plurality of segments which are made apart from each other during dehydration. A rotation motor (21) is used to move the moisture absorbing material (polymeric moisture absorbing material 24) between a moisture absorption region (14a) and a dehydration region (14b). In the dehydration region (14b), the moisture absorbing material (polymeric moisture absorbing material 24) is heated by the heater (25).

摘要： A dehumidifying device configured such that a dehumidifying material having absorbed moisture can efficiently release moisture. The dehumidifying device carries out dehumidification with a polymeric moisture-absorbing material that (i) exhibits hydrophilicity in a temperature range equal to or lower than a temperature sensitive point which is a given temperature and (ii) exhibits hydrophobicity in a temperature range higher than the temperature sensitive point. The dehumidifying device includes: a substrate to which the polymeric moisture-absorbing material is fixed; a heat generating member which heats, to the temperature range higher than the temperature sensitive point, the polymeric moisture-absorbing material that has absorbed moisture; and a moisture absorbing unit motor which rotates the substrate, so that the moisture, which has been absorbed by the polymeric moisture-absorbing material that is heated to the temperature range higher than the temperature sensitive point, is released as a waterdrop by a centrifugal force.
