The use of a sulfonated polyaramide, poly-(p-sulfophenylene- terephthalamide) (PPSA) was proposed for the preparation of ordered SWCNT films. 20 mg of PPSA and 5 mg of SWCNTs were mixed in 1mL of water and were ultrasonically agitated for 5 h To obtain homogeneously aligned films and evaluate their optical properties. A small portion of the resultant solution was cast on a glass substrate, and a film was obtained by a bar coater method. The prepared films appeared transparent and the average transmittance of 100 nm thickness of transmittance of 100 nm thickness of SWCNT/PPSA films over the visible region was close to 100%. Spectra were recorded at several randomly chosen locations in the sample, and other samples were measured to confirm reproducibility. The result assume that a SWCNT formed by high anisotropic π-conjugation shows a larger value of the order parameter than that of the liquid crystalline (LC) template.
