The instant application relates to nanogels or compositions that hold multivalent metal ions until some level of nanogel degradation has occurred, then slowly release the multivalent metal ions for gelation with carboxylate containing polymers. Compositions comprising such nanogels, together with polymers that can be crosslinked with multivalent metal ions, allow the deployment of such mixtures in various applications, and greatly increased gelation times.
本申请涉及纳米凝胶或组合物,可保持多价金属离子直至纳米凝胶发生一定程度的降解,然后缓慢释放多价金属离子与含羧酸盐的聚合物凝胶化。由这种纳米凝胶和可与多价金属离子交联的聚合物组成的组合物可将这种混合物用于各种应用,并大大延长凝胶时间。
