Interfacial activity
The hyper branched polymers of Hybrane®
are ideally suited for designing interfacial activity by combining different
structural elements (polar, a-polar, specific anchor groups, ionic and
nonionic surfactant groups).
In comparison to conventional linear (block) copolymers, the interfacial
activity of hyper branched polymers is enhanced by a reduced loss of entropy
upon adsorption at the interface. Like a spider or octopus, as opposed to a
snake or eel, the star shaped Hybrane® molecule is able to touch one side of
the interface with some legs of choice, leaving the other legs or the body
free to interact with the other side.
The following
presentation provides some more information regarding the interfacial
activity of Hybrane®.
