Abstract
New insights into the formation mechanism of a polymerized mesophase (space group Im3m) and its derived order mesostructured carbon phase (denoted FDU-16) were evidenced by a slight modification of its synthesis conditions using proton nuclear magnetic resonance (NMR) relaxometry (T2 spin–spin relaxation time), dynamic light scattering (DLS), small-angle X-ray diffraction (SAXRD), N2 physisorption (77 K), and scanning electron microscopy (SEM). The preparation of those materials is based on the self-assembly of a prepolymer (phenol-formaldehyde resin called resol) and a pyrolysable surfactant (Pluronic F127, PEO106PPO70PEO106). The former is the carbon precursor, and the latter is the pore structuring agent and also the porogen. The resol and the F127 solutions are usually mixed at room temperature before being heated at 65 °C to promote the polymerization of the resol into a polymerized mesophase that precipates. That phase is further carbonized into a mesostructured porous carbon. By a slight change of...
