Porous material is a kind of material with a certain size and quantity, the size of the pore size, quantity and distribution are the key factors that affect the performance of porous materials. Due to the porous materials with larger specific surface area, so it can be applied to many fields, such as a battery, adsorption and separation, catalysis and other, in industrial catalysis, they are very important for a class of catalysts and carriers. This article through evaporation guide self assembling method synthesized a series of 1-naphthol and 2-naphthol as carbon source of micro mesoporous composite, and examines in detail the electrochemical properties. The main work is as follows:1. The synthesis mechanism of 1-naphthol by evaporation guided self-assembly of carbon micro mesoporous composite material. A series of mesoporous carbon materials in different proportions were prepared.The effects of properties of 1-naphthol to investigate the effects of different proportion of naphthol content of carbon material. By changing the phenolic resin and naphthol and the ratio of F127, adjust the pore structure of the mesoscopic structure. F127 and phenolic resin and 2-naphthol and quality than 1:5, formed as the core of the PPO PEO as shell uniform cylindrical micelles. Volatilize alcohol, the phenolic resin with small molecular polymerization under 120 oC for heat polymerization to form larger molecules.2.Synthesis of 2-naphthol as the carbon source of micro mesoporous composite material.Preparation of a series of different proportions of 2-naphthol as carbon source of micro mesoporous composite dielectric porous carbon materials and to investigate the effects of different proportion of 2-naphthol content of carbon material properties. By changing the naphthol phenolic resin and the ratio of F127 with adjustable pore structure of mesoscopic structure. The preparation of porous polymer film.3 Electrochemical performance testThe electrochemical properties of a series of mesoporous carbon materials prepared by analysis of cyclic voltammetry, galvanostatic charge discharge test and AC impedance test. Specific process is: the electrochemical properties of the materials used CHI660 B type electrochemical workstation were tested, three electrode system, oxide composite oxide electrodes as the electrode, platinum electrode as auxiliary electrode, saturated calomel electrode(SCE) as the reference electrode study cyclic voltammetry performance. Examines the AC impedance, signal to the electrode system with small amplitude sine wave with different frequencies, analyzes the electrode system contains the dynamic process and mechanism, by equivalent circuit element parameters estimate the kinetic parameters of the electrode system. The results show that the phenolic resin, 2-naphthol doping the capacitive is the best, and the when the ratio of phenolic resin, 2-naphthol 9:1 is maximum capacitance, its value for 195 F/g.
