This invention provides a method for creating a large-scale of amphiphilic particles. The method includes: adding nanoparticles into a polycarbonate-based solution, adding a surfactant into the solution while performing ultra-sonication to generate polymer precipitation, creating at least one microsphere with the nanoparticles embedded onto it, subjecting the exposed hemisphere of the embedded nanoparticles to a further amphiphilic particles related modification, and dissolving the at least one microsphere in a polycarbonate-based solution in order to free said embedded nanoparticles from the at least one microsphere.

The invention relates to a process for preparing an organic solvent-based dispersion comprising a melt-blended network of an epoxy-functional and/or amino-functional polymer having a polymer-O—Si—O-polymer linkage and a polyolefin (co)polymer having carboxylic acid and/or carboxylic acid anhydride groups, the process comprising the steps of a) forming the melt-blended network from a prepolymer, a silane-functional compound and the polyolefin (co)polymer in the absence of a solvent, b) mixing the melt-blended network with an organic solvent to make the organic solvent-based dispersion, and c) cooling the organic solvent-based dispersion. The invention further relates to a coating composition and to a coated metal substrate.

A polymer dispersion is disclosed. The polymer dispersion includes a liquid crystal polymer powder, a polyamide acid, and a solvent. A solid content of the polymer dispersion includes the liquid crystal polymer powder and the polyamide acid. The liquid crystal polymer powder has a mass ratio of 20% to 30% in the solid content. The polyamide acid has a mass ratio of 70% to 80% in the solid content. The polyamide acid is obtained by mixing two kinds of diamines and two kinds of dianhydrides together, causing the diamines and the dianhydrides to be polymerized with each other. Both two kinds of diamines and two kinds of dianhydrides comprise a liquid crystal structure and a flexible structure respectively. A method of preparing the polymer dispersion, and a method for preparing a polymer composite film using the polymer dispersion are also disclosed.

A porous polybenzimidazole (PBI) particulate resin is disclosed. This resin is easily dissolved at ambient temperatures and pressures. The resin is made by: dissolving a virgin PBI resin in a highly polar solvent; precipitating the dissolved PBI in a bath; and drying the precipitated PBI, the dried precipitated PBI being porous. The porous PBI resin may be dissolved by: mixing a porous PBI resin with a highly polar solvent at ambient temperatures and pressures to form a solution.
