    Abstract: A method includes heating a sulfonated polyester resin in an organic-free solvent adding an aqueous solution of silver (I) ion to the heated resin to form a mixture and heating the mixture to effect the reduction of silver (I) ion to silver (0) in the absence of an external reducing agent. A composite includes a sulfonated polyester matrix and a plurality of silver nanoparticles dispersed within the matrix; the composite lacks trace residual byproducts from external reducing agents.

    Abstract: The present invention aims to provide an aqueous dispersion that contains particles of a fluoropolymer at high concentrations and has a less variable pH, and in which aggregates are less likely to be generated even after the aqueous dispersion has been stored for a long time. The present invention relates to an aqueous dispersion, including: particles of a fluoropolymer having an average primary particle size of 0.1 to 0.5 μm in an amount of 50 to 70% by mass; a nonionic surfactant in an amount of 2 to 10% by mass based on the amount of the fluoropolymer; and ammonium lauryl sulfate in an amount of 0.0001 to 1% by mass based on the amount of the fluoropolymer, wherein an amount of a fluorine-containing anionic surfactant is less than 10 ppm.
