聚合物复合膜的制备及吸液性能

由聚丙烯（PP）、聚乙烯（PE）制成的单层或多层微孔膜（PP，PP／PE／PP）具有良好的机械强度，且具备自关闭功能，已被广泛用作液态锂离子电池的隔膜，但PP，PP／PE／PP等微孔膜表面能低，难与塑料电极真正复合为一体，不能直接用于聚合物锂离子电池。因此在PP，PP／PE／PP等微孔膜表面涂敷一层具有黏结性质的过渡薄膜，兼顾两种材料的优点，有助于提高机械强度和将电极粘结起来的黏结力。聚合物复合膜是一种具有3层结构的复合膜，由两外层膜及中间膜组成。正丁醇不溶胀PVDF—HFP，可以丁醇为介质来测量复合膜的吸液率，该数据可作为膜孔率高低的判据，也可用于粗略判断膜电导率高低。

工艺参数对铀表面铝镀层热应力分布影响

为了防止铀的腐蚀，采用在铀表面磁控溅射镀铝，但使用中发现铝镀层内产生了较大的应力，影响镀层结合强度及使用性能。通常认为，薄膜内的应力有热应力和生长应力两种。文中通过改变沉积温度、镀层厚度以及镀层力学性能分数，研究它们对镀层热应力分布的影响，从而为改善铀表面铝镀层内热应力分布提供理论依据。     

Formation Mechanism and Orderly Structures of an Iron Film System Deposited on Silicone Oil Surfaces

A new iron film system,deposited on silicone oil surfaces by vapour phase deposition method,has been fabricated and its formation mechanism as well as orderly structures has been studied,It is found that the formation mechanism of the films obeys a two-stage growth model,which is similar to that to the other metallic films on liquid substrates,Large and orderly structures are observed in the continuous iron films.The experiments show that the orderly spatial structures result from the local material gathering in these nearly free sustained films.     

SURFACE METALLIZATION OF CENOSPHERES AND PRECIPITATORS BY ELECTROLESS PLATING

This paper reports the use of a colloidal Pd^0 catalysis system to metallize the surface of precipitators separated from coal fly-ash, and metals such as Cu, Ni etc. are deposited on the precipitators surface. Alternatively, according to the characteristic surface of cenospheres, an Ag coating catalysis system is adopted to first deposit Ag on the cenospheres surface, followed, if necessary, by the deposition of other metals such as Cu, Ni, etc. on the Ag coating to produce monolayer and multilayer metal-coated cenospheres. The surface characteristics and the morphologies of the metal coatings are examined in detail with scanning electron microscopy (SEM), energy dispersive spectroscopy (EDX) and X-ray photoelectron spectroscopy (XPS) techniques. It can be shown that the quality of metal coatings derived from the Aa coatina catalysis system, is better than that of the colloidal Pd^0 catalysis system.
