Hydrogels have attracted broad interest in view of their numerous different applications. Compared to 3D hydrogels, thin hydrogel films have higher thermal stability and mechanical durability, which introduces a number of new applications, for example, in the field of coating chemistry and for specific cell attachment. At the outset of this talk, I will present an elastic gel film formed by self-assembly of hydrophobic dipeptides, which is induced at an air-water interface via drop-casting. This kind of gel film is an excellent candidate for foam and emulsion stabilization. A wet foam system with long-term stability is then created, which will be the focus of the second part of this talk.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
