Manipulating three-dimensional gel network entanglement by thin film shearing.

Kumari, Harshita and Kline, Steven R. and Kennedy, Stuart R. and Garvey, Christopher and Raston, Colin L. and Atwood, Jerry L. and Steed, Jonathan W. (2016) 'Manipulating three-dimensional gel network entanglement by thin film shearing.', Chemical communications., 52 (24). pp. 4513-4516.


Vortex fluidic mediated shearing of supramolecular gels in thin films leads to complete disruption of fluorous bis-urea derived gels. Hydrocarbon analogues however, are only partially disrupted, which emphasizes the resistance of non-fluorous bis-urea gelators towards shear. The gel structures have been studied by combining the thin film shearing with small angle neutron scattering. This technique represents a novel approach to study the effects of external stimuli on self-assembled supramolecular gel networks.
