CAPMAT: Next generation MATerials via controlled CAPillary suspensions

Imagine mixing particles with two immiscible liquids and instantly producing a fluid whose rheology you can preset and tune. Capillary suspensions make this possible: a small volume of secondary liquid wets particle surfaces and forms a network of liquid bridges, radically transforming flow and mechanical properties. This tunability paves the way for innovative materials—from healthier foods and ocean remediation to affordable additive manufacturing. Achieving these advances requires deep insight into bridge formation and composition optimization. We aim to develop multiscale numerical models and novel experimental protocols to predict and control capillary suspension rheology, unlocking their full potential.
