Abstract: The current invention provides a novel method to synthesize a mono-disperse non-porous polymer particles with a unique gradient composition from the core to the shell. In particular, the present invention offers the flexibility to design the chemical and physical properties of different sections of the particle. This flexibility allows for significant latitude in the design of particles for analyzing a large variety of samples in different fields—through using these particles in different chromatography techniques including, but not limited to, ion exchange HPLC (e.g., bio-separation at different modes), reversed-phase HPLC, narrow bore and capillary HPLC, hydrophilic/hydrophobic interaction liquid chromatography, capillary electrochromatography separation, and two dimensional liquid chromatography.

Abstract: The present invention provides a manufacturing method of carbon nanotube conductive microspheres and conductive glue in comparison with a manufacturing method of carbon nanotube conductive microspheres provided by the present invention provides and the conventional “two-step method” which needs to prepare the plastic or resin microspheres and then plating the conductive metal, it is not necessary to respectively prepare the plastic or resin microspheres and the conductive layer, instead, the carbon nanotube are mixed in the polymer microspheres when the styrene monomer, the crosslinking agent and the initiator have a crosslinking reaction to form the polymer microspheres with a method of spray-granulation. Only one step is needed to prepare the conductive microspheres with carbon nanotube as the conductive medium, which can simplify the process, reduce the process, save cost. With mixing the carbon nanotube inside the polymer microspheres, the thermal mismatching between the carbon nanotubes and the resin can be illuminated, to ensure the conductive properties of conductive microspheres. Furthermore, the entire preparing process has no heavy metal salts; the bio-toxicity is reduced and no environmental pollution. The present invention provides a conductive glue, which comprises the carbon nanotube conductive microspheres manufactured by the manufacturing method of carbon nanotube conductive microspheres are easy to manufacture, lower cost, lower impact of thermal mismatching, great conductive properties, and no environmental pollution.
