pH dependence of water-solubility of single-walled carbon nanotubes treated by microplasma in aqueous solution
نویسنده
چکیده
Single-walled carbon nanotubes (SWCNTs) were solubilized by microplasma in pH-controlled aqueous solution. The SWCNTs were highly dispersed and solubilized in water under higher pH condition (pH > 9). Surface of the SWCNT was functionalized by carboxylate ion (-COO) and negatively charged during the microplasma treatment. A possible mechanism of water-solubility of SWCNT was briefly discussed.

There is great interest in using single-walled carbon nanotubes (SWNTs) as nanoscale probes and sensors in biological electronics and optical devices because the electronic and optical properties of SWNTs are extremely sensitive to the surrounding environments. A well-controlled modification of SWNT surfaces may provide unique interfaces that are sensitive to the biological variables such as pH...
