Novel polymer nanotube composites were fabricated by intercalating poly vinylpyrrolidone into Buckypaper from solution. This was carried out for both low 10k g/mol and very high 1.3M g/mol molecular weight polymers. Measurements of the polymer mass uptake as a function of time allowed the calculation of diffusion coefficients as 1.66 10−9 cm2/s and 3.08 10−12 cm2/s for the low and high molecula...

The fabrication process of buckypapers (BPs) made from stable suspensions of as-received or functionalized multi-walled carbon nanotubes (MWCNTs) with high purity (97.5 wt%, Baytubes), their characterization and their utilization towards novel biofuel cell electrode applications are reported. The BPs can vary in thickness between 1 μm and 200 μm, are mechanically robust, flexible, stable in sol...
