Rheo-SANS study of hydrogel mixtures during gelation under shear.

DOI

Small molecules known as low molecular weight gelators (LMWG) can self-assemble to form a network of fibres, which trap and hold a vast amount of water forming a gel. An increase in the acidity of the system can be used to trigger gel formation and during this process the way molecules are arranged in space changes as they assemble into fibres. We are particularly interested in gels formed from two types of LMWG. The behaviour of these soft solids when shear is applied is important both for real world applications and in the understanding of the structures formed. We will use small angle neutron scattering to investigate the sizes and shapes of structures formed within a solution of two LMWG while the gel is forming and while it is simultaneously sheared using a rheometer.
