Water absorption is a research area that focuses on studying the ability of materials to absorb and retain water. This property is important in various fields such as materials science, environmental engineering, and biotechnology. Understanding water absorption helps in developing materials with specific properties, such as moisture resistance, durability, and permeability. Researchers investigate factors influencing water absorption, including material composition, pore structure, surface chemistry, and environmental conditions. The findings from water absorption studies can be used to improve the performance and durability of materials in different applications.
