概括介绍了一些在高吸水凝胶基础上提高凝胶吸水速率和膨胀凝胶强度的方法以及近年来的相关研究状况,展望了制备吸液量大、吸液快且强度高的水凝胶的研究发展前景。
To achieve a superabsorbent polymer possessing high absorption capacity, high absorption rate and desired strength of swollen gel simultaneously, a great deal of efforts have been made in recent years. In this article, the latest investigations on the superabsorbent hydrogels with fast swelling rate and high mechanical strength are presented. Special attention is paid to the preparation techniques used to improve the swelling and responding rates as well as the strength of swollen gel. Also, the research work need to be done later is mentioned.
