Carbon nanotubes/graphene composites have superior mechanical, electrical and electrochemistry properties with carbon nanotubes as a hydrophobicity boosting agent. Their extraordinary hydrophobic performance is highly suitable for electrode applications in lithium ion batteries and supercapacitors which often employ organic electrolytes. Also the hydrophobic features enable the oil enrichment for the crude oil separation from seawater. The ever reported synthesis routes towards such a composite either involve complicated multi-step reactions, e.g., chemical vapor depositions, or lead to insufficient extrusion of carbon nanotubes in the chemical reductions of graphene oxide, e.g., fully embedding between the compact graphene oxide sheets. As a consequence, the formation of standalone carbon nanotubes over graphene sheets remains of high interests. Herein we use the facile flash light irradiation method to induce the reduction of graphene oxides in the presence of carbon nanotubes. Photographs, micrographs, X-ray diffraction, infrared spectroscopy and thermogravimetric analysis all indicate that graphene oxides has been reduced. And the contact angle tests confirm the excellent hydrophobic performances of the synthesized carbon nanotube/reduced graphene oxide composite films. This one-step treatment represents a straightforward and high efficiency way for the reduction of carbon nanotubes/graphene oxides composites.

井壁稳定性对于油气勘探开发过程中的安全高效钻井至关重要。本文介绍了一种可以在水基钻井液钻井过程中强化井壁稳定性的疏水型纳米二氧化硅(HNS),采用线性膨胀实验、滚动回收率实验和抗压强度测试研究了其井壁强化性能,利用zeta 电位、粒径、接触角、表面张力等测试和扫描电子显微镜(SEM)观察分析了井壁强化机理。此外,利用接触角法计算了HNS处理前后页岩表面自由能的变化。实验结果表明,HNS在抑制页岩膨胀和分散方面表现出良好的性能,优于常用的页岩抑制剂KCl和聚胺。与水相比,HNS可使膨润土试样的线性膨胀高度降低20%,对强水化页岩的回收率提高11.53 倍。更重要的是,HNS可有效防止页岩强度的降低。机理研究表明,HNS良好的井壁强化性能可归因于三个方面:首先,带正电荷的HNS通过静电吸附中和部分黏土表面的负电荷,从而抑制渗透水化作用;其次,HNS在页岩表面吸附后可形成具有微纳米层次结构的“荷叶状”表面,显著增加页岩表面的水相接触角,大幅度降低了页岩表面自由能,从而抑制表面水化;再次,毛细作用的减弱和页岩孔隙的有效封堵减少了水的侵入,对井壁稳定有利。本文所述的方法对于抑制页岩的表面水化和渗透水化提供了一种新途径。

蒸汽压力和超疏水纳米复合涂层对微电子器件可靠性的影响 Article

由于高蒸汽压力可能导致微电子器件在高温和高湿度环境中失效,蒸汽压力的描述和模拟对研究微电子器件的湿度可靠性至关重要。为了最大程度地减小湿度的影响,可以在器件外表面涂抹一层超疏水涂层,以防止水分渗入。但是,超疏水涂层提高微电子器件可靠性的具体机制目前仍没有完全被理解。本文首先介绍了微电子高分子材料蒸汽压力的现有的一些理论。笔者还根据实验结果论述了超疏水涂层在防止水蒸气进入器件方面的机制和有效性。本文重点讨论了两个理论模型:基于微观力学的全场蒸汽压力模型和对流扩散模型。这两种方法都已成功用于说明无涂层样本的实验结果。但是,当器件上涂有超疏水纳米复合涂层时,笔者仍发现器件质量增加,其原因很可能是水蒸气可以透过超疏水涂层渗入。这种现象导致人们对超疏水涂层的有效性产生怀疑。根据理论和实验结果,笔者认为需要提出一种新的理论来理解水蒸气如何渗透超疏水涂层。
