Carbon nanospheres from polyacrylonitrile-based latexes

摘要：

A facile way to prepare carbon nanospheres with a narrow size distribution was developed. Polyacrylonitrile (PAN)/poly(methyl methacrylate) (PMMA) composite latexes were first synthesized by seed mini-emulsion poly-merization. Then, the latexes were used as the precursors to prepare carbon materials via successive oxidization and carbonization treatments. DLS, TEM, AFM, XRD and Raman spectrometry were used to characterize the size, morphology and structure of the nanoparticles. The result shows that carbon nanospheres with sizes less than 50 nm can be obtained from PAN/PMMA composite latexes.
