1. Enhanced Collective Electron Transport Behavior in Au Nanoparticles
Self-Assembled in the Poly(4-vinylpyridine) Nanodomains of
a Poly(styrene-b-4-vinylpyridine) Diblock Copolymer Ultra Thin Film
Conventional, (b) high-resolution, and (c) cross-sectional TEM images, obtained
without staining, of a thin film of 48% (Au NPs/P4VP)-b-PS. (d) Cross-sectional TEM
image of a thin film of 48% Au NPs/homo-P4VP.
Collective electron transport behavior of Au NPs sequestered in the spherical P4VP nanodomains was quasi 1-D, as opposed to the 3-D behavior displayed by Au NPs that had been dispersed randomly in P4VP.

2. Hierarchically Organized Nanoparticle Mesostructure Arrays Formed in Block Copolymer-Nanoparticle Mixtures
Redissolved
In toluene
The localization of nanoparticles in block copolymer will have more potential for novel functional applications, such as next generation catalysts, nanosenors, photonic bandgap materials, organic memory devices and nanostructured solar cells.
