A composition that includes an activatable aggregate is described herein. The aggregate has a core and a shell. In some embodiments, when the aggregate is exposed to acoustic energy, the core of the aggregate includes a hydrogel that is capable of absorbing a relatively large amount of water. The core of the aggregate is covalently bound to a shell of linear aliphatic moieties. The aggregate is synthesized to minimize the amount of water in the core, prior to exposure to acoustic energy. Methods of hydrating using the compositions are also provided.
本文描述了一种包含可激活聚合物的组合物。该聚合物具有一个核心和一个外壳。在某些实施例中,当该聚合物暴露于声能时,其核心包含一种能够吸收相对大量
水的
水凝胶。该聚合物的核心与一层线性脂肪族基团的外壳共价结合。在暴露于声能之前,通过合成该聚合物来最小化核心中的
水量。还提供了使用这些组合物进行
水合的方法。
