Direct synthesis of ordered mesoporous polymer/carbon nanofilaments with controlled mesostructures
- 233 Downloads
One-dimensional mesoporous polymer/carbon nanofilaments with controlled mesostructures have been prepared by an infiltration process of phenolic oligomers/surfactant into anodized alumina membranes followed by carbonization. Transmission electron microscopy (TEM), nitrogen sorption and X-ray diffraction (XRD) investigations show that as-prepared polymer nanofilaments possess ordered mesoporous structure tunable from circular hexagonal to cubic and concentric lamellar mesostructures. After carbonization, carbon nanofilaments with corresponding circular hexagonal, cubic and concentric lamellar mesoporous structure are obtained.
