综述了近年来石墨烯制备工艺的研究进展及其在聚丙烯改性领域的应用。采用改性的Hummers法先制备氧化石墨烯,向氧化石墨烯的超声分散液中滴加硝酸,再进行超声水热还原反应可以得到石墨烯粉体。电阻值不同且厚度不同的石墨烯薄膜可用于电子设备的散热件,低电阻值区域用于天线辐射体可以兼顾天线的辐射特性和散热件的散热性能。将氧化石墨烯悬浮液旋涂于基底上喷涂铜粉后,除去基底可以得到高导电率石墨烯。添加石墨烯等添加剂可以提升茂金属聚丙烯电力管熔接点的拉伸强度。 相似文献

A type of silicone adhesive was used for bonding anti-irradiation cover glasses to space solar cells. A new adhesion process for solar cells was designed, and implemented by means of an automated coating and bonding system based on an industrial robot. On the basis of non-Newtonian fluid theory, flow models of three sub-processes were created, and the commercial finite element analysis code Adina was employed to simulate the whole process. The purpose of the investigation was to acknowledge the mechanism of the adhesion process and identify correlative factors that influence the adhesion quality, to provide a basis for optimization of the adhesion process. A simulation platform was created, to make it possible to evaluate or predict the adhesion quality of space solar cells when the dimensions of the solar cells and the adhesive were changed. 相似文献

Dye-sensitized solar cells (DSSCs) based on disulfide/thiolate (T2/T−) redox couples have attracted remarkable attention due to their high efficiency and low cost. As an indispensible part of DSSCs, counter electrode (CE) design plays a crucial role in high efficiency DSSCs. This mini-review paper selectively reviews the recent advances in T-mediated DSSCs using novel CE (namely cathode) materials, mainly including noble metal platinum (Pt), carbon materials, transition metal compounds (TMCs), polymers, and hybrids, thus highlighting the merits and demerits of alternative Pt catalysts, and the prospects and challenges of Pt-free CEs for the development of high-performance and low-cost DSSCs. 相似文献
