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。

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.

Nickel based super-alloys are widely employed in aircraft engines and gas turbines due to their high temperature strength, corrosion resistance and, excellent thermal fatigue properties. Conversely, these alloys are very difficult to machine and cause rapid wear of the cutting tool, frequent tool changes are thus required resulting in low economy of the machining process. This study provides a detailed review of the tool wear mechanism in the machining of nickel based super-alloys. Typical tool wear mechanisms found by different researchers are analyzed in order to find out the most prevalent wear mechanism affecting the tool life. The review of existing works has revealed interesting findings about the tool wear mechanisms in the machining of these alloys. Adhesion wear is found to be the main phenomenon leading to the cutting tool wear in this study.
