The two polymers differ in the length of the hydrophilic moiety. Then, monodisperse carbon nanospheres (MCNS) were obtained via the carbonization of as-prepared composites, followed by KOH activation. A dense coating of the PPO blocks on the nanotube surface is determined with the PEO chains extended from the cylindrical core-shell structure. To promote their homogenous dispersion by preventing agglomeration of the SWCNT, at first, we used three different surfactants-sodium dodecyl sulfate (SDS-anionic), cetyltrimethylammonium bromide (CTAB-cationic), and Pluronic F108 (nonionic). The increased solubility in water of compounds like diazepam and indomethacin may be due to the micellar solubilization by Synperonic F-108. Unbound nisin was then removed by repeated washing (sonication, centrifugation and re-suspension in phosphate buffer). Ungraded products supplied by Spectrum are indicative.

Small angle x-ray scattering (SAXS) experiments on as-received and purified Pluronics revealed that the inter-micellar distance upon micellar ordering depends not on the polymer concentration. Thus, when Pluronic F108 is taken up by the PS surface from solutions of low concentration, all three blocks appear to adhere to the surface as long as there is free space available. Proper dispersion of the resulting sample was confirmed by. To compare between different temperatures and to avoid batch‐to‐batch variations, an electroporation experiment using the incubation times giving the highest. surfactant, Pluronic® F108, stabilizes silicone microparticles likely due to the strong association of the hydrophobic polypropylene oxide block with silicone [15]. 物理化学学报, 2000, 16(12): 1093-1102.
