Highly Elastic Supramolecular Hydrogels Using Host–Guest Inclusion Complexes with Cyclodextrins
摘要:
Supramolecular hydrogels, which are cross-linked via host guest interactions, show high-performance physical properties, such as elasticity and toughness. Herein we prepare a supramolecular hydrogel without chemical crosslinker. The supramolecular hydrogel was prepared by polymerization of the inclusion complexes between beta-cyclodextrin acrylamide and adamantane acrylamide monomers. The beta-cyclodextrin adamantane gel (beta CD Ad gel) shows a high stretching property (990%). The initial strain (0%) is restored in several minutes for a beta CD Ad gel stretched to 180% of the initial strain without altering the physical history. However, chemically cross-linked poly(acrylamide) does not show the reversible stretching property. These results indicate that host guest interaction inside the supramolecular hydrogel plays an important role in the shape recovery properties.

A process for producing an aqueous ink for inkjet printing capable of giving an elevated print density of printed matters, being improved in fixability to the material to be printed, water resistance and improved storage stability and scarcely scorching onto a printer head. This process comprises dissolving a salt-forming group-having polymer and a hydrophobic dye in a water-insoluble organic solvent to obtain a solution, adding water and a neutralizing agent optionally together with a surfactant to the solution to ionize the salt-forming group of the polymer, emulsifying the resulting mixture, and removing out the solvent from the emulsion to obtain an ink containing an aqueous dispersion of the polymer particles in which the dye has been encompassed.
