Abstract

Supramolecular hydrogels can spontaneously undergo syneresis through fibre-fibre interactions and expel significant amounts of water upon aging. In this process, the hydrophobicity of fibres which regulates the 3D-rearrangement of the self-assembled structures during syneresis is important. Here, we show that we can control over the hydrophobic microenvironment of gels by incorporating organic salts into the gel fibre involving co-assembly enabling control of the macroscopic gel volume phase transition.
