Supramolecular hydrogels can control the 3D-rearrangement of self-assembled structures and achieve water expulsion and volume phase transition by altering the hydrophobicity of the fibers.
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 the hydrophobic microenvironment of gels by incorporating organic salts into the co-assembled gel fibres thereby enabling control of the macroscopic gel volume phase transition.
