Description

In this lecture, we will introduce key concepts of soft matter, under the perspective of their interfaces.

The field of soft condensed matter investigates the multiscale structure of matter, in which thermal effects drives phase behavior and transport properties. It is an interdisciplary field, which explores a broad variety of materials : from the historical core of the soft matter – macromolecules, colloids, polymers, liquid crystals, gels, membranes, wetting –, divided matter — granular systems, foams, emulsions, … —, towards biological materials and the latest developments on active matter, self-assembly, molecular origamis, and micro- and nano-fluidics. Soft matter therefore lies at the interface of several fields, physics, chemistry, materials, biology. It plays a key role in the development of an interdisciplinary fundamental physics.

The lecture will introduce the essential concepts of soft matter and interfaces : adsorption, wetting, van der Waals and entropic force, osmosis, … as well as its dynamics. We will accordingly introduce the required theoretical tools, which couple statistical physics approches (phase transition, fluctuations, Brownian motion, …) and physics of continuum media (capilarity, wetting, hydrodynamics, elasticity, electro-dynamics of interfaces, ….). In particular, we will view the domain under the perspectives of scaling approaches, which allow to rationalize properties of sometimes very complex phenomena .
We will illustrate these concepts by studying a number of experiments and phenomena. To cite a few : Lotus effect and superhydrophobic phenomena, splashes and wetting, teapot effect,capillary adhesion and granular matter, molecular friction at inerfaces, membranes fluctuations, critical Casimir interactions, active matter and bacteria, jamming transition, superlubricity of carbon nanotubes and nanoscale transport, molecular origamis, etc.
