A superabsorbent polymer (SAP) is a special polymer material that can absorb up to 500 times its own weight of pure water, but has a problem that it does not biodegrade itself and cause environmental pollution. Therefore, we aim to prepare a biodegradable SAP by using biomass‐based IA. The SAP must be able to retain absorbed water and absorb water under a given pressure. We have carried out studies to improve the surface hardness of the SAP to enhance absorption of water under a given pressure by surface‐crosslinking. Four types of surface‐crosslinkers, ethylene glycol diglycidyl ether (EGDGE), ethylene carbonate (EC), 1,4‐butanediol (BD), or glycerol, were used. We confirmed the water absorption capacity of the SAP by measuring its centrifuge retention capacity (CRC) and absorbency under load (AUL). The structural characteristics of the SAP were confirmed by attenuated total reflection (ATR) and X‐ray photoelectron spectroscopy (XPS), and the surface characteristics were confirmed by scanning electron microscopy (SEM).

根据表面交联剂的类型，制备可生物降解的高吸收性聚合物并测量吸收性能的变化

超吸收性聚合物（SAP）是一种特殊的聚合物材料，可以吸收高达其自身重量500倍的纯净水，但存在一个问题，即它自身不会生物降解并造成环境污染。因此，我们旨在通过使用基于生物量的IA来制备可生物降解的SAP。SAP必须能够保留吸收的水并在给定压力下吸收水。我们已经进行了一些研究，以改善SAP的表面硬度，以通过表面交联在给定压力下增强对水的吸收。使用了四种类型的表面交联剂：乙二醇二缩水甘油醚（EGDGE），碳酸亚乙酯（EC），1,4-丁二醇（BD）或甘油。我们通过测量SAP的离心保留能力（CRC）和负载吸收率（AUL）确认了SAP的吸水能力。
