The present application relates to the technical field of electrophoretic particles, more particularly to an electrophoretic particle, a preparation method therefor, and an application thereof. The electrophoretic particle includes a shell layer and a core layer, which is wrapped in the shell layer. The core layer includes a plurality of core particles, and the density of the core particles is lower than a density of the shell layer. The structure of the plurality of the core particles makes the shell layer wrapping on surfaces of the plurality of the core particles form a folded structure, thus increasing a surface area of the core layer and improving the bonding tightness between the shell layer and the core layer, and making the shell layer of the resulting electrophoretic particle have relatively strong tightness.

An electrophoretic medium comprises a plurality of core-shell particles and a non-polar fluid. The core-shell particles comprise an organic pigment particles core and a shell comprising a metal oxide layer and a silane layer. The metal oxide layer may have a thickness of 0.4 to 2 nm. It may be formed using a fluidized bed reactor by inserting the organic pigment into the reactor as a powder bed, contacting the powder bed with a gaseous stream comprising a metal oxide precursor and an inert gas, and contacting the powder bed with a gaseous stream of a reagent and an inert gas. The silane layer is formed from a silane compound comprising a first functional group, wherein the first functional group reacts with the metal oxide.

This invention relates to non-bleeding, non-staining occult particles for use in granular or powdered laundry care compositions such as laundry detergents, laundry aids, and fabric care compositions. The occult particles are comprised of a clay carrier and a coloring agent and are characterized as being substantially indiscernible when contained in the laundry care composition.

The disclosed technology relates generally to material systems which include a plurality of particles and methods of making the same. The particles have a core and a shell which encapsulates the core and has at least one atomic element not included in the core. The cores of the particles have a median maximum dimension that is less than 10 microns and a median of at least one axial dimension that is between 10 nm and 500 nm. The shells of the particles have a median thickness that is less than 100 nm, a silicon concentration that is between 10% and 50% on the basis of the weight of the shells, and an aluminum concentration that is between 0.01% and 5% on the basis of the weight of the shells.

The present invention relates to a laundry detergent composition comprising a particle comprising hueing agent and clay. The particle can be incorporated into laundry detergent products, such as a laundry detergent powder. The particle exhibits an excellent storage stability profile with very little bleeding of the hueing dye from the particle, exhibits excellent fabric deposition of the hueing dye during a laundering process without causing any spot staining of the fabric, and does not impact the visual appearance of a laundry detergent powder when incorporated therein.

An electrophoretic medium comprises a plurality of a first type of charged particles in a non-polar liquid. Each of the plurality of the first type of charged particles has a core and a shell. The core comprises an organic pigment and a graphene oxide layer. The shell comprises an organosilane layer and a polymeric layer. The electrophoretic medium may be incorporated in a color electrophoretic device to improve its electro-optic performance.

In various embodiments, the present invention is directed to a facile one-pot reverse emulsion process to assemble core-shell nanoparticles (CS-SMNPs) into bright and noniridescent photonic supraballs. In one or more embodiments, the present invention is directed to core-shell nanoparticles having an inner high refractive index (RI) core and an outer low RI shell. In one or more embodiment, the present invention includes core-shell nanoparticles using high RI (1.74) melanin cores and low-RI (1.45) silica shells. In various embodiments, these nanoparticles may be self-assembled into bright and noniridescent supraballs using a scalable one-pot reverse emulsion process. According to various embodiments of the present invention, it is possible to generate a full spectrum of structural colors with the combination of only two ingredients, synthetic melanin and silica.
