摘要： Nanoparticle composites and nanocapsules for guest encapsulation and methods for synthesizing same. One synthesis method includes providing a nanoparticle template; and forming a shell on the nanoparticle template by polymerizing a monomer on the nanoparticle template to form a nanoparticle composite defined by the shell and the nanoparticle template. Another synthesis method includes providing a nanoparticle template; forming a shell on the nanoparticle template by polymerizing a monomer on the nanoparticle template; and dissolving the nanoparticle template to thereby form a hollow nanocapsule defined by the shell. Another synthesis method includes providing a nanoparticle template carrying a guest molecule; and forming a shell on the nanoparticle template by polymerizing a monomer on the nanoparticle template to thereby encapsulate the guest molecule. This method can also include dissolving the nanoparticle template to form a nanocapsule defined by the capsule shell material, wherein the guest material resides in the nanocapsule.

摘要： Conductive polymeric particles can be formed by mixing a monomer, carbon black and a block copolymer, wherein the block copolymer contains an A block that is miscible with said monomer and a B block that anchors to the surface of the carbon black, such as polystyrene or a derivative of polystyrene. A polymerization initiator is added to the mixture and bulk polymerization is effected until about 5 to about 30 weight percent of the monomer has been polymerized. This partially polymerized product is then dispersed in water and further polymerized.
