Abstract

High Internal Phase Emulsion hydrogels are prepared from waterborne poly(N-isopropylacrylamide) nanogel dispersions which are non-covalently crosslinked through 2-ureido-4[1H] pyrimidinone (UPy) quadruple hydrogen bond groups. The reversible UPy crosslinks allow for the HIPE-hydrogels to be molded into objects which are thermo-responsive in nature.

摘要

高内相比乳液水凝胶是由水性聚（N-异丙基丙烯酰胺）纳米凝胶分散体制备的，该分散体通过 2-尿嘧啶-4[1H]嘧啶酮（UPy）四重氢键基团非共价交联。可逆的 UPy 交联使得 HIPE 水凝胶可以被模塑成具有热响应性质的物体。
