Processes for continuously coalescing particles from an aggregated particle slurry are disclosed. The aggregated particle slurry is heated, then coalesced by raising the pH. The coalesced particles are homogenized and exit as a coalesced particle slurry. A multi-screw extruder is used for the coalescing. These processes are useful for providing coalesced particles such as toner compositions.

Sensors employing elastomers enhanced with electrically conductive 2D nanoparticles are provided. The nanoparticles are formed by applying shear to layered materials present in elastomer precursors (e.g., elastomeric monomer(s) and/or curing agent(s)). Subsequent exfoliation of the layers occurs directly within the precursor and/or curing agent. The cured elastomer nanocomposites can be employed for electrochemical sensing, flexible touchpads, pressure sensors, and wireless sensors, amongst other applications.

In some aspects, the present disclosure pertains to systems for forming hydrogel compositions, the systems comprising a first reservoir containing an iodinated polymer composition that comprise an iodinated polymer having multiple cyclic imide ester groups, a second reservoir containing a buffered diluent solution having a first pH that comprises water, a first buffering agent and a polyamine compound, and a third reservoir containing a buffered accelerant solution having a second pH that is higher than the first pH and comprises water and a second buffering agent. Other aspects of the present disclosure pertain to methods of using such systems for forming hydrogel compositions.

The present invention relates to a kind of pigment preparation, in particular to a modified layered silicate novel barrier and shielding pigment and its preparation method. It is a layer silicate with exchangeable anticorrosive ions as a template, using metal oxides or metal salts, inorganic acids to synthesize nano-spherical zinc phosphate, phosphate, molybdate, borate or tungstate, with rare earth cerium, strontium, lanthanum or praseodymium doped modification of the pigment. The invention uses silicate as a template to effectively control the agglomeration of nanoparticles during the liquid phase deposition process, avoiding the multiple cleaning and sewage treatment processes required by using surfactants and solvents. What is more valuable is lamellar silicic acid. The salt itself has certain anti-corrosion properties and is economical. At the same time, the physical barrier and exchangeable anti-corrosion ions of the lamellae further improve the anti-corrosion properties of the pigment, making the pigment highly active and shielding.
