Header and Body 3


This material platform is a hydrohobic block - hydrophilic polyelectrolyte block copolymer that forms a simple 1D periodic lamellar structure. This results in a responsive PC hat can be tuned via swelling of the hydrophilic layers by contact with a fluid reservoir. The glassy hydophobic layer forces expansion of the hydrophilic layer along the layer normal, yielding extremely large optical tenability through changes in both layer thickness and index refraction.
