Hydrogels are described which have delayed swelling properties. A hydrogel is formed by reacting a hydrophilic monomer, a first crosslinker, and a second crosslinker. The first crosslinker defines the volume expansion of the hydrogel in an aqueous environment, and the second crosslinker, which is biodegradable, can modulate the swelling rate of the hydrogel in aqueous solution. In its dry state, the hydrogel (xerogel) is flexible and elastic. It can also be cut with a knife or scissors, or molded or shaped by hand. The ready shapeability of the xerogel by trimming or compression affords a superior hydrogel for medical applications.
描述了具有延迟膨胀特性的水凝胶。水凝胶是通过反应亲水性单体、第一交联剂和第二交联剂形成的。第一交联剂定义了水凝胶在水环境中的体积膨胀,而第二交联剂,它是可生物降解的,可以调节水溶液中水凝胶的膨胀速率。在干燥状态下,水凝胶(干凝胶)是柔软和有弹性的。它也可以用刀或剪刀切割,或者通过手工塑造或成形。通过修剪或压缩的便捷成形性为医疗应用提供了优越的水凝胶。
