Abstract
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.
Claims7
A moisture absorbing material comprising:
- a dried product of a polymer gel,
- the polymer gel including
- a stimuli-responsive polymer whose affinity with water changes reversibly in response to an external stimulus and
- a hydrophilic polymer, and
- the stimuli-responsive polymer and the hydrophilic polymer forming an interpenetrating polymer network structure or a semi-interpenetrating polymer network structure.
