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

(a) 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.

Prepare to submit

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.
