Wood scantlings were coated with polyaniline (PANI) during the in situ polymerization of aniline with ammonium peroxydisulfate in an aqueous medium. The coating was made in hydrochloric or phosphoric acid solutions in both the absence and presence of stabilizers, poly(N-vinylpyrrolidone) or colloidal silica. The PANI-coated wood was placed in a flame or in a furnace operating at 400 or 6008C, and the decrease in the mass was determined. The wood coated with PANI was less reduced in its mass than uncoated samples and was converted to charcoal rather than to ashes. The deposition of related polymers, polypyrrole and poly(1,4-phenylenediamine), provided similar protection against heat exposure. Fourier transform infrared and Raman spectra of the residues after the burning of PANI-coated wood were compared. The soaking of wood in PANI colloids did not result in similar protection of wood against fire; the coating of the cellulose fibers with PANI during the polymerization was needed for the enhanced stability of wood at elevated temperatures. The concept of carbonization processes at the surface layer of PANI-coated cellulose fibers leading to the formation of carbonaceous microtubes is offered to explain the improved stability of wood against flame and heat exposure.

“…However, poor solubility of PANI in water or organic solvents is always an inherent major obstacle in making the assays. Although solid state PANI-based colorimetric sensors, like filter paper coated with PANI, have been developed to conquer this problem, the sensitivity is still limited, because the PANI coating blocked most of the original structure feature of filter paper [22].…”

This study describes the preparation of colloidal poly(aniline-co-ethylaniline) by chemical copolymerization. The product was characterized morphologically using SEM and TEM, chemically using FTIR and optically UV-Vis. The prepared polymer was then tested for the antibacterial properties against Gram-negative bacteria; Pseudomonas aeruginosa and Gram-positive bacteria; Staphylococcus aureus. The antibacterial properties were assessed by disk diffusion, minimum inhibitory concentration (MIC), Downloaded by [New York University] at 23:31 24 July 2015 2 minimum bactericidal concentrations (MBC) and bactericidal kinetic methods. It was found that the MIC and MBC values of poly(aniline-co-ethylaniline) against P. aeruginosa were 0.62 mg/ml and 1.25 mg/ml, respectively. The values of MIC and MBC for S. aureus were 0.62 mg/ml.
