A special feature of the model colloids made these findings possible: their softness can be tuned very finely over a large area by altering the length ratio between the hydrophilic and
hydrophobic components of the molecule threads.
The model system developed by researchers from the Jülich Centre for Neutron Science is made up of water and block copolymers — thread - like molecules with both a hydrophilic and
a hydrophobic component.
The bigger
the hydrophobic component is, the more polymers will clump together and dense, hard spheres are formed.

components by integrating a
hydrophobic coating with the electromagnetic interference shields used to protect sensitive electronics.
