In the future, high-absorbent polymers (SAP) will develop in the direction of high performance, compounding, functionalization, and degradability. High performance is to improve the water absorption speed, salt tolerance, gel strength and thermal stability of the resin on the basis of ensuring the excellent water absorption and water retention properties of SAP, so that SAP has multiple pressure absorption and excellent liquid permeability. Features. It can penetrate and spread quickly and repeatedly, and is suitable for the development of lightweight and thin diapers in the future. The compounding is a combination of inorganic materials with inorganic materials or other polymer materials to prepare a highly water-absorptive material having excellent performance and low cost. Functionalization is the addition of functional ingredients to SAP to have specific functions, such as antibacterial functions; biodegradable polymer materials are also a development direction of SAP.
