Background
Traditional methods of buckypaper production involves the use of surfactants to disperse carbon nanotubes into aqueous solutions. It was found that filtering this suspension allowed the nanotubes to pack together in a paper-like mat, thus coining the term “buckypaper” (bucky being the reference to the buckminsterfullerene molecule). The problem was the difficulty in removing the surfactant afterwards, where the surfactant has been linked with cell lysis and tissue inflammation.
Acid oxidation of carbon nanotubes can also be used in filtration to form buckypaper, but requires a high degree of surface acidic groups in order to obtain efficient dispersal in aqueous solution.

Famous quotes containing the word background:
“Pilate with his question “What is truth?” is gladly trotted out these days as an advocate of Christ, so as to arouse the suspicion that everything known and knowable is an illusion and to erect the cross upon that gruesome background of the impossibility of knowledge.”
—Friedrich Nietzsche (1844–1900)
“... every experience in life enriches one’s background and should teach valuable lessons.”
—Mary Barnett Gilson (1877–?)
“I had many problems in my conduct of the office being contrasted with President Kennedy’s conduct in the office, with my manner of dealing with things and his manner, with my accent and his accent, with my background and his background. He was a great public hero, and anything I did that someone didn’t approve of, they would always feel that President Kennedy wouldn’t have done that.”
—Lyndon Baines Johnson (1908–1973)
