SWNT Composite Fibers (SCF)
Abstract
We achieved the synthesis, processing, properties, and morphology of polymeric nanocomposites made using highly carboxylated, soluble, ultra-short (lengths less than 60 nm) single-walled carbon nanotubes (US-SWNTs). The epoxy composite system reinforced with 0.5 wt% or I wt% of US-SWNTs has shown an average 15% increase in tensile modulus and 50% increase in tensile toughness over those of the neat epoxy, demonstrating the reinforcement efficacy of US-SWNTs in a thermoset matrix. Copolymerization of short (avg. length 60 nm) carboxylic acid functionalized SWNTs with PBO oligomers was successfully carried out in a mixed solvent of polyphosphoric acid and methanesulfonic acid (MSA) in the presence of P2O5 at 3.3 wt% concentration and 150 0C. The SWNTs were homogeneously distributed throughout the films of copolymerized products. Reaction-induced crystallization of oligomers was applied for the preparation of single-walled carbon nanotubes (SWNTs)/poly(p-oxybenzoyl) (POB) crystals using SWNTs as a nucleating agent. The research, detailed in the publications and prior technical reports, is larger than 2 MB.
