摘要: An emulsion-like polymerization technique called admicellar (AP) was used to encapsulate a thin film of copolymer on the surface multi-walled carbon nanotubes (MWCNTs). A water-soluble component sodium acrylate and non-water soluble methyl methacrylate were form films nanotubes. Various ratios polymer combinations formulated MWCNT’s understand stability composition heterogeneity MWCNT’s. Encapsulated MWCNTs characterized using SEM, energy dispersive spectroscopy (EDS), thermal analysis FT-IR. Analytical studies indicate formation MWCNTs. Monomer conversion rate reactivity analyzed high performance liquid chromatography (HPLC) by Fineman-Ross Kelen-Tudos methods. The combination showed an alternating tendency azeotropic at 0.6 monomer. encapsulated stable in aqueous media with onset aggregate beginning 40 days for copolymer.
