The dehumidification of air stream moisture in closed environments can be realized by the use of super adsorbent materials with high capacity for water uptake [1]. The transport in a selective fashion of water molecules across porous materials enables to reduce the humidity of an air stream. The application of such materials has the advantage over many commercially available desiccants. Because such materials are nontoxic and can absorb water molecules, allowing the independent control of the humidity. Therefore, it is essential to develop new super adsorbent materials for air dehumidification. For example, a technical solution proposed in this study deals with the producing of a specific super adsorbent matrix based on polymer-molecular sieves composites. In this respect, polymers were deposited onto the rigid structure of different molecular sieves yielding the composite structured networks with synergistic properties. According to the theoretical screening, such composites may be used (for water uptake) as efficient desiccants alternative to other available adsorbents. Moreover, the efficiency of these materials was proved by water adsorption experiments. In summary, the polymer-inorganic composites are important for controlling air dehumidification process.
