FIG. 1.

(Color online) Time-lapsed reflection spectra of CLC in chamber as acetone vapor evaporate. Insets show corresponding transmission optical images obtained by POM and variation of CLC pitch during absorption of acetone vapor.

FIG. 2.

(Color online) (a)-(h) Time-lapsed transmission optical images of CLC-CNT hybrid in a chamber, obtained by POM, as acetone vapors diffuse into the CLC-CNT hybrid. Insets in (a), (c), and (f) are the corresponding photographs with transmission optical images. Scale bar in (b) represents 100 μm. Optical images (a)-(i) were obtained using the same objective lens.

Image of FIG. 3.
FIG. 3.

(Color online) Measurement of the change in electrical resistance and reflection wavelength: (a) photograph of CLC-CNT hybrid and its electrical resistance before acetone vapor diffuses into CLC-CNT hybrid; (b) photograph of CLC-CNT hybrid and corresponding electrical resistance after acetone vapor diffuses into CLC-CNT hybrid (diffusion time = 115 s); (c) the change in reflection wavelength and electrical resistance as a function of vapor concentration. Inset in (a) is the comb like electrode.
