Figure 3. LC phases of GO in non-polar suspending media.

Figure 3

(a,b) Low-magnification (a) and high-magnification (b) optical micrographs between crossed polarizers of GO suspensions in diethyl ether at a concentration of 1 wt%. (c,d) Low-magnification (c) and high-magnification (d) micrographs of viscous GO/PDMS composite precursors with 1 wt% of GO before thermal cross-linking. (a,c) Scale bars, 100 μm. (b,d) Scale bars, 20 μm. Samples were prepared by transferring a drop of GO suspension onto a glass slide and confining the dispersion with a cover slip. For the GO/PDMS sample, the GO/PDMS suspensions were first dried in the vacuum oven at room temperature for 15 min and then the viscous mixture was transferred onto a glass slide and confined with similar cover slip. The observed textures reflect the formation of small monodomains of nematic LC phase.
