阴极电泳涂料用高固体分丙烯酸树脂的合成

采用甲基丙烯酸异冰片酯(IBOMA)、甲基丙烯酸二甲胺乙酯(DMAEMA)等(甲基)丙烯酸酯类单体合成阴极电泳涂料用高固体分自交联型丙烯酸树脂。研究发现,引入低表面张力、带非极性多环酯基的IBOMA可降低树脂的黏度,提高合成树脂的固体质量分数到75%甚至更高;当单体的滴加时间控制在3～3 5h,采用m(偶氮二异丁腈)∶m(过氧化苯甲酸叔戊酯)=1∶(0 3～0 5)的混合引发剂,w(混合引发剂)=2%～4%时,能获得相对分子质量大小及分布适宜的水溶性高固体分自交联聚合物;研究聚合物水溶性和涂膜交联性的影响因素发现,w(DMAEMA)=16%、w(甲基丙烯酸羟乙酯)=15%、w(N 丁氧甲基丙烯酰胺)=6%时,树脂的水溶性较佳,涂膜的交联度可达90%;引入了丙烯酸作为共聚物自交联的潜催化剂,差示扫描式量热法(DSC)分析表明,w(丙烯酸)=1%时,可显著降低树脂的固化反应温度。

采用不同锰源合成尖晶石LiMn2O4正极材料

The spinel LiMn2O4 cathode material was synthesized with the solid-state reaction method. Four manganese compounds including electrolytic manganese dioxide (EMD), MnCO3, Mn3O4 and nano-EMD were used as Mn sources while LiOH·H2O was used as the uniform Li source. The crystal structure characteristics of these samples produced were investigated by means of XRD, SEM, particle size distribution analysis and specific surface area testing. Their electrochemical properties were also studied by comparing their specific capacity, charge and discharge efficiency and cycle performance.

直接和间接电合成制备出的高铁酸钾的物理和电化学性能

K2FeO4 powders were synthesized by the ex-situ and in-situ electrochemical methods, respectively, and characterized by infrared spectrum （IR）, scanning electron microscopy （SEM）, X-ray powder diffraction （XRD） and BET. Their electrochemical performances were investigated by means of galvanostatic discharge and electrochemical impedance spectroscopy （EIS）. The results of physical characterization showed that the two samples have simi- lar structural features, but their surface morphologies and oriented growth of the crystals are different, which results in smaller specific surface area and lower solubility of the ex-situ electrosynthesized K2FeO4 sample. The results of discharge experiments indicated that the ex-situ electrosythesized K2FeO4 electrode has much larger discharge capacity and lower electrode polarization than the in-situ electrosynthesized K2FeO4 electrode. It was found from the results of EIS that lower electrochemical polarization might be responsible for the improvement on the discharge performance of the ex-situ electrosynthesized K2FeO4 electrode.
