摘要： This invention relates to separators for batteries and other electrochemical cells, especially lithium-ion batteries, having a shutdown mechanism. The separator is a laminate that contains a nonwoven nanoweb and a porous layer composed of a plurality of thermoplastic particles having particle size smaller than the mean flow pore size of the nanoweb. The shutdown layer melts and starts to flow at a desired temperature, and restricts the ion flow path, resulting in a substantial decrease in ionic conductivity of the separator at the desired shutdown temperature, while leaving the separator intact.
摘要翻译：本发明涉及具有关机机构的电池用分离器和其他电化学电池，特别是锂离子电池。隔板是含有非织造纳米网和多个由多个尺寸小于纳米网的平均流孔径的热塑性颗粒构成的多孔层的层压体。关闭层熔化并开始在所需温度下流动，并且限制离子流动路径，导致分离器在所需的关闭温度下的离子电导率的显着降低，同时使分离器完好无损。

摘要： An acoustically absorbent ceiling tile includes a core of acoustically absorbing material having two major surfaces, and a facing for covering the core on at least one major surface. The facing comprises a porous flash spun plexifilamentary film-fibril sheet having a coherent surface and comprising a plurality of pores having a pore diameter between about 100 nm and about 20,000 nm and a mean pore diameter of less than about 20,000 nm. The facing has highly diffuse reflectance of light, and a reflectance of greater than about 86%. The use of the facing improves the acoustic absorption of ambient sound at frequencies below about 1200 Hz. The facing provides a barrier to moisture and particles including microorganisms so that the ceiling tile is suitable for use in environments in which cleanliness is critical.
摘要翻译：吸声天花板瓦片包括具有两个主表面的吸声材料芯和用于在至少一个主表面上覆盖芯的面。面包括具有粘结表面的多孔快速纺丝丛状薄膜原纤维片，并且包含孔径在约100nm至约20,000nm之间且平均孔径小于约20,000nm的多个孔。面具有高的漫反射光，反射率大于约86％。使用面部可以改善低于约1200Hz频率的环境声音的吸声。面对水分和颗粒（包括微生物）提供屏障，使得天花板砖适用于清洁度至关重要的环境中。

摘要： A nanoweb that contains a plurality of nanofibers wherein the nanofibers contain a fully aromatic polyimide that is characterized by having a crystallinity index (CI) and a degree of imidization (DOI). The product of the DOI and the CI is between 0.08 and 0.25 or above a lower limit to obtain a desired tensile strength and/or toughness. The nanoweb may for example have a tensile strength per unit basis weight of greater than 15 kg/cm2 per gram per square meter unit of basis weight.
