摘要：

Small molecular gels (SMGs) have drawn much attention due to their unique properties which can be used in wide range of applications. In this work, the two-component hydrogels based on intermolecular interaction were prepared by the mixing appropriate ratios of melamine (M) and nitrilotriacetic acid (N) in pure water. These obtained hydrogels, which own a three-dimensional (3D) supramolecular structure, responded to several external stimuli such as temperature, pH and halogen ions. Otherwise, the two-component hydrogels mixed with M and N in organic-water mixtures were studied by calculating the Hansen Solubility Parameters of the solvents, a gelation range of the known two-component could be defined. The untested solvent lied in this known range might be gelled by M and N, which is a useful model to identify the gelation and the particular application of a suitable two-component hydrogels.
