摘要： A method for synthesizing a polymer/pigment hybrid latex through sulfur-free and soap-free in-situ reversible addition-fragmentation chain transfer (RAFT) emulsion copolymerization includes the following: dispersing a pigment with a reactive emulsifier to prepare a pigment dispersion; synthesizing an amphiphilic sulfur-free ω-vinyl-terminated polymethyl methacrylate (PMMA) macromolecular RAFT agent in-situ on a surface of pigment particles through catalytic chain transfer polymerization (CCTP); and adding an acrylate monomer dropwise, allowing in-situ sulfur-free RAFT polymerization on a surface of pigment particles through the RAFT agent, and adjusting a structure and a composition of an encapsulated polymer layer to obtain a series of uniformly encapsulated and stably dispersed polymer/organic pigment hybrid latexes. The new hybrid latex prepared through sulfur-free and soap-free in-situ RAFT emulsion copolymerization has the characteristics of high dispersion stability, high pigment encapsulation efficiency, clear encapsulated polymer layer sequence, controllable structure, etc., which is suitable for surface encapsulation modification of various pigments.

摘要： The disclosure provides a production method capable of producing a hollow fine particulate containing a fluorine-containing resin and having a large average particle size. The production method includes a step A of dispersing a solution containing a fluorinated monomer and a non-polymerizable solvent into water to provide a dispersion; a step B of polymerizing the fluorinated monomer to provide a phase-separated fine particulate containing a fluorine-containing resin; and a step C of removing the non-polymerizable solvent in the phase-separated fine particulate to provide a hollow fine particulate.

摘要： The present disclosure relates to methods for making polyols, esters, and surfactants. Generally, a carboxyl-containing molecule is reacted with an epoxide-containing molecule to obtain a hydroxylated ester. If multiple epoxide groups are present in the epoxide-containing molecule, the resulting molecule can also be considered a polyol. The hydroxyl groups can be further ethoxylated to obtain a surfactant/stabilizer.

摘要： An example display assembly includes: an outer substrate; an inner substrate; a first electrode and a second electrode disposed between the inner substrate and the outer substrate in a spaced apart relationship; and at least one substantially planar microstructure between the first and second electrodes, the microstructure containing an electrophoretic media, and wherein the electrophoretic media comprises a first chemical entity and a second chemical entity, wherein the first and second chemical entities are to be induced to reversibly interact to switch between a separated state and an optically active state in response to a change in an electromagnetic field applied to the electrophoretic media by the first and second electrodes to change an optical property of the electrophoretic media.
