ELECTROPHORETIC MEDIA INCLUDING CHARGE CONTROL AGENTS COMPRISING QUARTENARY AMINES AND UNSATURATED POLYMERIC TAILS
Improved formulations of electrophoretic media that can be incorporated into displays, front plane laminates, inverted front plane laminates, or color changing films. The formulations include a non-polar fluid, a plurality of first charged particles, and charge control agents (CCA) including a quaternary amine and an unsaturated polymeric tail comprising monomers of at least 10 carbon atoms in length. The formulations show improved switching speeds, as well as a larger dynamic range at low temperatures (i.e., below about 0 C.), where compared to state-of-the-art electrophoretic media.
Method for coating a substrate
A method for coating a substrate includes the steps of: forming a conductive coating layer on a surface of a substrate so as to form a semi-product; submerging a conductive sheet and the semi-product into an electrophoresis medium that includes charged colloid particles; and applying a voltage on the conductive sheet or the semi-product to form an electric field among the conductive sheet, the semi-product, and the electrophoresis medium, so that the colloid particles move along the electric field toward the semi-product and an electrophoretic covering layer formed by the charged colloid particles is thus deposited on the electrophoretic covering layer.
VEHICLE INTERIOR COMPONENT HAVING COATED FRAME FOR ADHESIVE BONDING WITHOUT PRIMER
Disclosed are embodiments of a vehicle interior component. The vehicle interior component includes a glass article having a first major surface and a second major surface in which the second major surface is opposite to the first major surface. The vehicle interior component also includes a frame comprising a support surface and a coating disposed on the support surface of the frame. The vehicle interior component further includes an adhesive joining the second major surface of the glass article to support surface of the frame. The adhesive is bonded directly to the coating.
FUNCTIONALIZED QUINACRIDONE PIGMENTS
Quinacridone pigments that are surface-functionalized with glycidyl methacrylate, maleic anhydride, or 4-methacryloxyethyl trimellitic anhydride to create a functionalized pigment. The functional groups are then activated to bond hydrophobic polymers, thereby coating the pigment with the hydrophobic polymers. The quinacridone pigments can be used for a variety of applications. They are well-suited for use in electro-optic materials, such as electrophoretic media for use in electrophoretic displays.
Display characteristics with memorability
A display unit of the present invention includes, in an insulating liquid (1), migrating particles (10), and a porous layer (20) formed using a fibrous structure (21), and the fibrous structure (21) includes non-migrating particles (22) having light reflectivity different from light reflectivity of the migrating particles (10) and being at least partially modified with a surfactant.
