Electroosmotic technology is widely used in dehydration applications, such as soil consolidation and sludge dewatering. It has the potential to be used as a dehumidification tool combined with solid desiccant—proposed as a novel dehumidification fin. In this study, composite desiccants are prepared by mixing macroporous silica gel with liquid desiccant and placed in the environmental chamber to determine the adsorption capacity. Both the type and the concentration of the liquid desiccant are compared on the amount of moisture adsorbed in the composite materials. Further, the selected composite samples are installed between two humidity chambers to test the dehumidification rate under the electroosmotic effect. The main factors, such as the size of particles, the intensity of electric field, and the density of material, on the dehumidification rate are compared and discussed in detail.
