Abstract
Nitrogen-doped mesoporous carbons (NMCs) with controlled nanostructures are attractive materials for catalytic and electrochemical applications. In this study, poly(4-vinylpyridine)-block-poly(2,2,2-trifluoroethyl methacrylate) (P4VP-b-PTFEMA) was synthesized and blended with resol to form self-assembled microphase-separated structures. Strong interactions between the pyridine moieties of P4VP and resol enabled the preservation of the nanostructures during carbonization, resulting in the formation of NMCs with well-defined mesostructures.
By tuning the block copolymer composition and blend formulation, various nanostructures, including gyroid, cylindrical, and golf ball-like morphologies, were successfully fabricated. The obtained structures were characterized by small-angle X-ray scattering (SAXS), scanning electron microscopy (SEM), and nitrogen adsorption measurements. These findings demonstrate that the self-assembly of P4VP-b-PTFEMA/resol blends provides an effective strategy for the precise control of nanostructures in nitrogen-doped mesoporous carbons.
