| Summary: | 碩士 === 國立中山大學 === 材料與光電科學學系研究所 === 107 === Carbon materials is a hot research in recent years, because of its wide range of application and close to our life. In this study, we used two kinds ABA type block copolymers as template respectively, Poly(ε-Caprolactone)-b-Poly(Ethylene Glycol)-b-Poly(ε-Caprolactone) (PCL-b-PEO-b-PCL) and Poly(Lactide)-b-Poly(Ethylene Glycol)-b-Poly(Lactide)(PLA-b-PEO-b-PLA), and blend with phenolic resin(Resol), curing after blending by evaporation induced self-assembly(EISA). Finally, remove the templated by thermal treatment to obtain the large mesoporous carbon. The structure and characterization of large mesoporous carbon identified by small-angle X-ray scatting(SAXS) and transmission electron microscopy(TEM), specific surface area and nitrogen adsorption isotherm measured by BET analysis. And application properties of the large mesoporous carbon, we check by carbon dioxide capture and electrochemical measurement.
The prepared large mesoporous carbon has a specific surface area 609.7m2/g, pore size 53.7 nm, carbon dioxide capture capacity of 6.19mmol/g at 273K, and the capacitance is 120F/g, the cycle test showed efficient stabilities with 90% retentions after 5000 times.
