Polybenzoxaxine (PBZ), a new type of additional-cure phenolic system, has been successfully synthesized by a facile quasi-solventless method and used as a precursor for producing nanoporous carbon. In this work, we aim to study the effect of non-ionic (Synperonic NP30) and cationic (CTAB) surfactants on porous structure of porous arbon derived from polybenzoxazine. Inter-connected structure of mesoporous carbon with mesopore diameters in the range of 15.57-36.07 nm was obtained by using different concentrations of CTAB. In addition, carbon nanospheres with the size of 50-200 nm were also obtained through the emulsion process. The mesopore diameters started to decrease when the carbon nanospheres were formed at the CTAB concentration of equal to or exceeding 0.030 M. By using Synperonic NP30 as a surfactant, the properties of the obtained nanoporous carbon were shifted from mesoporous materials for the reference nanoporous carbon (no surfactant added) to obviously microporous materials at higher concentrations of Synperonic NP30 (0.009 M - 0.180 M). The carbon microspheres with the diameter size of about 2.5 m were also obtained through the emulsion process when the concentration of Synperonic NP30 was reached at 0.180 M.
