Figure 1. (a) TEM micrograph of a phase-separated 600 Å thick, PS-b-PMMA copolymer film. The light areas correspond to the PMMA phase. Image dimensions were 1.7 µm × 1.75 µm. (b) TEM micrograph of dodecanethiol-coated gold nanocrystals on a microphase-separated PS-b-PMMA substrate, deposited form a dilute solution in toluene/ethanol. Image dimensions were 360 nm × 350 nm.
Figure 2. TEM micrographs of dodecanethiol-coated gold nanocrystals deposited on a phase-separated PS-b-PMMA block copolymer film. (a) Disperse coverage observed for deposition from dilute solution. Image dimensions 615 nm × 690 nm. (b) Dense coverage resulting from deposition from a more concentrated solution. Note the presence of nanocrystals on the PMMA phases. Image dimensions 205 nm × 230 nm. S0743-7463(98)00110-3 CCC: $15.00 © 1998 American Chemical Society Published on Web 02/24/1998
