摘要：
Stimuli-responsive hydrogels have attracted much interest recently [1]. In this paper, we report a pH- and electrolyte-responsive hydrogel based on a crosslinked poly(aspartic acid). The lightly crosslinked, high molecular weight sodium polyaspartate impart extremely high water absorbency and can be used as a superabsorbent [2]. It is derived from a naturally occurring non-toxic amino acid, L-aspartic acid. A hydrogel based on poly(as-partic acid) possesses most of the features of poly(acrylic acid) hydrogels plus improved biodegradability. We expect it to be useful in a variety of applications including personal care and biomedical areas.
