文章采用有机包覆法对纳米TiO2进行表面改性,制备了2,4-甲苯二异氰酸酯(TDI)/TiO2纳米杂化材料。采用红外光谱(FT-IR)、热质量损失分析(TGA)、静态接触角(CA)、透射电镜(TEM)及分散性实验等手段对纳米TiO2和TDI/TiO2纳米杂化粒子进行分析和表征。红外光谱和热质量损失分析显示,TDI以物理吸附和化学键合的方式存在于纳米TiO2的表面,并形成了有机包覆层。经计算,每nm2约有4.0个羟基参与化学反应,化学包覆率达57.97%。静态接触角数值表明,TDI/TiO2纳米杂化粒子具有很强的疏水性能,与水的接触角达147°。分散性实验显示,TDI/TiO2纳米杂化粒子在基础润滑油中分散稳定,静置20 d未出现分层现象。

采取机械剥离10次,得到低维度GaS.利用325nm激发光,在200~600K变温条件下测量了多层GaS拉曼光谱的温度特性,观察了A11g和A21g在不同温度下的拉曼频移.实验结果表明,GaS的拉曼峰位和峰宽均随温度变化,峰位移动的原因为晶格受热膨胀,晶格振动和晶格常量发生改变;而峰宽的改变则归因于晶格振动剧烈导致声子寿命的缩短.同时,否定了GaS在高温下层间解耦,即否定了高温下多层变单层的可能性.

以苯并咪唑、不同链长的卤代烷烃、硫酸二甲酯为原料,合成了几种烷基苯并咪唑阳离子表面活性剂。通过IR1、HNMR对产物结构进行表征,测定了所得产物的表面活性和发泡性能,并计算出产物的饱和吸附量及饱和吸附面积。结果表明,合成的N-辛基、癸基、十二烷基、十四烷基苯并咪唑阳离子表面活性剂的最低表面张力随烷基链增长而降低,但N-十六烷基苯并咪唑阳离子表面活性剂的最低表面张力却高于十四烷基苯并咪唑阳离子表面活性剂;合成的表面活性剂中,十二烷基苯并咪唑阳离子表面活性剂的发泡性能较佳,但所有的表面活性剂的泡沫稳定性均较差。

目前,国内外有关N-长链烷基苯并咪唑对钢缓蚀作用的研究鲜见报道,苯并咪唑无毒,环境友好,可替代苯并三氮唑,利用价值大。合成了一系列不同链长的N-烷基苯并咪唑阳离子(NBIC),并研究了其对碳钢的缓蚀性能和作用机理。通过失重法、极化曲线法、扫描电镜分析以及对吸附热的计算等考察了40℃下N-烷基苯并咪唑阳离子在1.0mol/LHCl中对碳钢的缓蚀作用。NBIC在较低浓度(20mg/L)下就表现出优异的性能,以N-正十二基苯并咪唑阳离子(N12BIC)效果最好。随着浓度的增加,缓蚀效率增加,当N12BIC浓度为50mg/L时,缓蚀率达到97.15%。吸附热数据表明在碳钢表面的吸附行为既包含化学吸附又有物理吸附。极化曲线测试表明,NBIC是一种以抑制阴极反应为主的混合型缓蚀剂。
