Abstract:
Supramolecular copolymer hydrogels were prepared by mixing 1 and the additives 2-8, and their rheological properties were evaluated. It was found that additive 3 reinforced the mechanical strength of the resultant hydrogel most efficiently, increasing the yield stress of SCH 1+3 about fourfold. The optimal mixing between the glyco-lipid hydrogelator 1 and the additive 3 sufficiently enhanced the mechanical strength of the resultant SCH, which improved the handling of the SH on the large scale. These results indicate that supramolecular copolymerization can provide the supramolecular hydrogel with desired properties and/or functions.
