Grazing Incidence X-ray Scattering Studies on Nanoporous Structure in Poly(3-hexylthiophene) thin film |
| 초록 |
Block copolymers via ionic interaction, (P3HT-NH3+)-b-(PS-SO3-)s, were successfully synthesized, simply by blending P3HT-NH2 with PS-SO3H in toluene. The self-assembly behavior of the (P3HT-NH3+)-b-(PS-SO3-) thin film was observed by atomic force microscopy (AFM) and transmission electron microscopy (TEM). By exploiting the pH-sensitive ionic interaction, the PS-SO3- domains were selectively etched with ethyl acetate/triethylamine, cleaving the ionic interaction between P3HT-NH3+ and PS-SO3- segments, to obtain the target nanoporous P3HT-NH2 films. The porosity of the films was confirmed by AFM, scanning electron microscopy (SEM). To understand morphology of P3HT polymer in the thin film, grazing incidence X-ray scattering (GIXS) was measured from ultra small angle to wide angle region. |
