New polymer film sheds light on opalescent phenomenon

Abstract:
A new flexible polymer opal has defied the conventional explanation for colour generation in opals, a recent study reports.

Researchers at the University of Southampton, UK, and Deutsches Kunststoff-Institut (DKI) in Darmstadt, Germany, have created a polymer opal, so-called because of the regular arrangement of polystyrene spheres that make up its micro-structure, that they believe has scaling-up potential. In contrast, natural opals are made from stacked silica spheres.
The project, led by Professor Jeremy Baumberg of Southampton, developed a self-assembling process to produce the film.

In a departure from previous methods, the team fabricated the film by compressing a polymer melt, which, through shear-flow alignment, created the ordered arrangement, or lattice*, of core-shell nanospheres.
