Development of natural waste fiber desiccant paper coated with biopolymeric material for energy efficient dehumidification

The quest for efficient dehumidification solutions in modern industries emphasizes the need for advancements in measuring the cleanliness of products and processes, particularly in the context of environmental sustainability. This research explores the potential of natural waste fiber desiccant paper coated with biopolymeric materials. These emerging materials in the field of dehumidification technology offer an attractive blend of cost-effectiveness and eco-friendliness. This initiative not only provides a practical solution for moisture control but also contributes to the reuse of materials, echoing global efforts in sustainable development. The research introduces the fabrication and evaluation of desiccant paper, assessing its morphological structure and moisture reduction capabilities using scanning electron microscope (SEM), Fourier-transform infrared spectroscopy (FTIR), energy dispersive X-ray analysis (EDX), wettability, and moisture evaluation tests. SEM analysis highlighted surface morphologies and porosity showing that the desiccant exhibits a porous structure suitable for moisture absorption. FTIR analysis revealed the presence of hydroxyl groups on desiccant samples with broad peaks around 3200-3500 cm(-1) indicating that moisture has been absorbed. EDX analysis showed a high carbon content in desiccant sample with presence of calcium and chloride. Wettability tests indicated that the coated polymeric material contributes to maintaining the structure of the desiccant, preventing fiber separation, and swelling. The moisture evaluation test demonstrated a significant decrease in relative humidity, from 92 to 48% with a notable reduction in humidity ratio from 0.0183 to 0.0096 kgkg(-1). These findings underscore the effectiveness of desiccant in their moisture absorbing properties, porosity, and eco-friendly advantages over conventional materials.
