An electrophoretic display comprises a fluid and a plurality of nanoparticles having diameters substantially less the wavelengths of visible light such that, when the nanoparticles are in a dispersed state and uniformly dispersed throughout the fluid, the fluid presents a first optical characteristic, but when the nanoparticles are in an aggregated state in which they are gathered into aggregates substantially larger than the individual nanoparticles, the fluid presents a second optical characteristic different from the first optical characteristic. The electrophoretic display further comprises at least one electrode arranged to apply an electric field to the nanoparticle-containing fluid and thereby move the nanoparticles between their dispersed and aggregated states. Various compound particles comprising multiple nanoparticles, alone or in combination with larger objects, and processes for the preparation of such compound particles, are also described.
A process for forming a nanoparticle assembly comprising a nanoparticle secured to an object via a linking group, which process comprises:
A process for forming a nanoparticle assembly comprising first and second nanoparticles secured to each other via a linking group, said first and second nanoparticles bearing charges of opposite polarity, which process comprises:
An electrophoretic display comprising a fluid, a plurality of a first species of nanoparticles in the fluid and a plurality of a second species of nanoparticles in the fluid, the first and second species of nanoparticles differing in electrophoretic mobility, the display having a viewing surface through which the nanoparticle-containing fluid can be viewed, the display having:
An electronic display comprising, in order:
A nanoparticle assembly comprising a nanoparticle having a diameter substantially less than the wavelengths of visible light, an object separate from the nanoparticle, and a flexible filament connecting the nanoparticle and the object, such that at least one optical characteristic of the nanoparticle varies with the spacing between the nanoparticle and the object.
A nanoparticle assembly comprising a plurality of nanoparticles and a polymer chain, the nanoparticles being spaced from one another along the polymer chain, the polymer having first and second conformations such that the distances between adjacent nanoparticles along the chain differ in the first and second conformations and at least one optical characteristic of the nanoparticle assemblies differs between the first and second conformations.
