Nanomaterials can enhance absorbency through several mechanisms:
Physical Adsorption: The physical interaction between the absorbent and the substance being absorbed is amplified due to the increased surface area. Chemical Absorption: Nanoparticles can be engineered to have functional groups that react chemically with the target substance, making absorption more effective. Capillary Action: In nanoporous structures, capillary action can help pull liquids into the material, increasing the rate and amount of absorption.
