Gelation kinetics and equilibrium rheology of dual networks from LMWG and surfactants

On the one hand, low Molecular Weight Gelators (LMWGs) are molecules with a molecular mass of less than 1000 g/mol that are capable of non-covalent self-assembly into a 3D network of fibers, i.e.  into a gel network. To form a gel, the gelator must have a - usually very low - solubility in the continuous phase. On the other hand, surfactants can reduce the interfacial tension by adsorption at the interface in heterogeneous systems. At certain concentrations, surfactants can form micelles with different shapes such as spheres, lamellae, rods and worm-like. The worm-like micelles have the ability to form a viscoelastic network with typical rheological behavior. Combining LMWGs and surfactants may thus lead to the formation of a dual network consisting of gel fibers and worm-like micelles. The main objective of this project is to formulate such a dual network and to study its kinetics. Ideally the gelator is newly developed / synthesized by project partners. A better understanding of the interactions between LMWGs and surfactants will help in developing new formulations with a wide range of applications in field such as beauty care and home care products.
