AbstractPoly(acrylic acid) (PAA) and poly(allylamine hydrochloride) (PAH) were used to tailor the microstructure of single-walled carbon nanotubes (SWNTs) in both aqueous solutions and dry composite films. Microstructural changes were achieved as the pH of aqueous suspensions were changed, as evidenced by elevated suspension viscosity, scanning electron microscopy and electrical conductivity measurements. The ability to tailor microstructure is useful for aqueous SWNT processing and solid polymer nanocomposites.

Regenerated cellulose/poly(acrylic acid) composite films have been synthesized for wound dressing applications. The water absorbency of these films was studied as a function of amount of cross-linker N,N′-methylenebisacrylamide and cellulose contents in the feed mixture. The samples, having different compositions, showed tensile strength and percent elongation in the range of 9.98×105 to 13.40×105 N/m2 and 110 to 265, respectively. The water vapor transmission rate (WVTR) for various films was found to be in the range of 2.03 to 7.18 mg/cm2/h. These films were loaded with antibacterial drug miconazole nitrate and their release was studied in the physiological pH at 37°C. The release data was found to fit well the diffusion controlled Higuchi model. Finally the films demonstrated fair antibacterial and antifungal action, thus establishing their strong candidature as wound dressing materials.
