3.2. Morphological studies
Optical images and scanning electron micrographs were used to
depict the morphology of nanocomposites treated cotton fabrics.
Fig. 2 shows the different visual appearance and morphology of
control cotton, GO-cotton, PANI-cotton and PANI-GO-cotton fabric
respectively. From the low magnification version in the optical
images of each case, the interlaced structure ofwarp and weft yarn
can be clearly observed, meanwhile, the deposited GO nanosheet
causes copper brown color of the cotton fabric surface (Fig. 2(b))
from the white surface in Fig. 2(a), the polyaniline coated cotton
fabric in Fig. 2(c) tends to dark-green feature. Furthermore, the
presence of GO nanosheet can darken the dark-green of polyaniline
coated cotton fabric as shown in Fig. 2(d) indicating the well
dispersion of nanocomposites. In addition, polyaniline deposition
process is benefit to reduce the surface hairiness of cotton fabric as
indicated in the optical images of PANI-cotton and PANI-GO-cotton
fabric.
It can be also obviously seen from the micrograph of Fig. 2(b)
that GO nanosheet well dispersed onto the cotton fabric surface
after vacuum filtration deposition process. Moreover, it was
indicated from Fig. 2(c) and (d) that the PANI and PANI-GO
granular membrane can be uniformly deposited on cotton fabric
surface under the proper preparation conditions through in-situ
chemical polymerization of aniline. It can be further seen from
Fig. 2(d) that the PANI-GO nanocomposites granular membrane
obtained performs more evenly distributed on PANI-GO-cotton
fabric surface than that of PANI-cotton fabric. Thus it can be
considered that the high surface area of GO nanosheet is benefit to enhance the uniformity of polyaniline in-situ chemical polymerization
on the surface of PANI-GO-cotton fabric.
