1Synthesis and characterization of PMMA/Al_2O_3 composite particles by in situ emulsion polymerization显示文摘In order to improve its dispersibility,superfine alumina(Al2O3) was encapsulated with poly(methyl methacrylate)(PMMA) by in situ emulsion polymerization.It was found that only when the concentration of sodium dodecyl sulfate(SDS) was much higher than its critical micelle concen-tration,could PMMA/Al2O3 composite particles with high percentage of grafting(PG) be prepared.The same results were obtained between the experimental and stoichiometric amounts of tris(dodecylbenzenesulfonate) isopropoxide(NDZ),indicating that single-molecule-layer adsorption had taken place between NDZ and Al2O3.Analysis using FTIR,TEM and XPS showed that PMMA/Al2O3 composite particles with core-shell structure had been successfully synthesized by in situ emulsion polymerization.Compared to Al2O3,thermal stability and dispersibility of the composite particles showed marked improvement.Hui Liu Hongqi Ye Tianquan Lin Tao Zhou 2008Particuology2008,6,3:9

3Electrodes with Electrodeposited Water-excluding Polymer Coating Enable High-Voltage Aqueous Supercapacitors显示文摘Aqueous supercapacitors are powerful energy sources,but they are limited by energy density that is much lower than lithium-ion batteries.Since raising the voltage beyond the thermodynamic potential for water splitting(1.23 V)can boost the energy density,there has been much effort on water-stabilizing salvation additives such as Li_(2)SO_(4) that can provide an aqueous electrolyte capable of withstanding~1.8 V.Guided by the first-principles calculations that reveal water can promote hydrogen and oxygen evolution reactions,here,we pursue a new strategy of covering the electrode with a dense electroplated polymerized polyacrylic acid,which is an electron insulator but a proton conductor and proton reservoir.The combined effect of salvation and coating expands the electrochemical window throughout pH 3 to pH 10 to 2.4V for both fast and slow proton-mediated redox reactions.This allows activated carbon to quadruple the energy density,a kilogram of nitrogen-doped graphene to provide 127 Watt-hour,and both to have improved endurance because of suppression of water-mediated corrosion.Therefore,aqueous supercapacitors can now achieve energy densities quite comparable to that of a lithium-ion battery,but at 100 times the charging/discharging speed and cycle durability.Wujie Dong Tianquan Lin Jian Huang Yuan Wang Zhichao Zhang Xin Wang Xiaotao Yuan Jie Lin I-Wei Chen Fuqiang Huang 2020Research2020,,1:1

5SiO2 stabilizes electrochemically active nitrogen in few-layer carbon electrodes of extraordinary capacitance显示文摘Pyrrolic and pyridinic N dopants can dramatically increase the electrochemical activities of carbon and conducting polymers.Although N-doped conducting polymers suffer from rapid degradation,their carbon counterpart of extraordinary capacitance has remarkable rate performance and cycling endurance thanks to carbon’s excellent electrical conductivity.But high nitrogen content and high electrical conductivity are difficult to achieve in a high-surface-area carbon,because the high chemical vapor deposition(CVD)temperature required for obtaining high conductivity also destabilizes under-coordinated pyrrolic and pyridinic nitrogen and tends to lower the surface area.Here we resolve this dilemma by using SiO2 as an effective N-fixation additive,which stabilizes the N-rich nano few-layer sp2-carbon construct in1000℃CVD.This enables a scalable sol-gel/CVD fabrication process for few-layer carbon electrodes of extraordinary capacitance(690 F g^-1).The electrodes have excellent rate performance and can maintain90%of their initial capacitance after 30,000 cycles,thus potentially suitable for practical applications.Feng Xu Tianquan Lin Jian Huang I-Wei Chen Fuqiang Huang 2020Journal of Energy Chemistry2020,29,10:0
