Superabsorbent polymer (SAP) hydrogel is a material with a three-dimensional polymer network structure, containing water hundreds of times more than their own weight. It is used in various fields such as baby diapers, cosmetic, and agriculture. Recently, droughts caused by abnormal weather have made water supply difficult for plants, causing problems all over the world as forests and trees disappear. One solution to this problem is to use a soil water retention enhancer made with SAP hydrogel that can provide continuous moisture to plants. However, the general soil water retention enhancers use organic crosslinking agents. It has an inhomogeneous network structure, which limits its ability to water absorption capacity. In this study, we report a high water absorption capacity soil water retention enhancer based on inorganic crosslinker. The SAP hydrogel using the inorganic crosslinker was prepared and the swelling characteristic of the SAP hydrogel was studied.
