Polypyrrole (PPy) was deposited on cellulose via vapor phase polymerization, in which co-vapor solvents were employed with pyrrole monomer, such as methanol, ethanol, benzene, water, toluene and hexane. The main properties of the resultant PPy/cellulose composites were significantly influenced by the nature of the co-vapor solvent. Specifically, the polar solvents such as methanol and ethanol highly affected the conductivity of the composites. The specific capacitance of the composites, which is a measure of the surface area, mainly depended on the non-polar solvents, such as benzene, toluene, and hexane. It is anticipated that understanding the role of the co-vapor in vapor deposition polymerization may provide an efficient route to tuning the properties of conducting polymer composites. |
