G8-2012 New low surface energy materials 145825

低表面能材料（LSEM）是通过将表面层附着到基材上而获得的。低表面能的原因是界面层的基本化学结构：控制表面性质的能力是化学结构的直接结果。自抗湿表面首次开发以来，在表面活性剂添加剂中始终需要使用长氟化尾（>7 x CF2/CF 3基团）。目前LSEM有许多应用，例如印刷、涂装、粘合、金属电镀、乳化/悬浮（医疗、化妆品、食品包装等），洗涤（电子产品、衣服等）、防雾和防水表面（自清洁窗户、防水纺织品、防雪、防雾表面、纸张、纤维等）。因此，LSEM的开发和优化引起了人们的广泛关注，并且通过氟化表面可以获得各种有用的LSEM。不幸的是，由于氟碳化合物（FCs）的持久性和生物累积性，这会产生严重的环境后果。[Food Addit Contam. 2005，10，1023-31，Environ. Sci. 2006，40，32-44]。如下所述，该项目的核心是碳氢化合物（HC）表面活性剂的智能程序化分子设计，这将产生与不受欢迎的FC相似的表面特性。

Low surface energy materials (LSEMs) are obtained by attachment of surface layers to substrates. The cause of low surface energy is the underlying chemical structure of the interfacial layers: the ability to control surface properties being the direct consequence of chemical structure. Since the first development of anti-wetting surfaces, it has always been necessary to employ long Fluorinated tails (>7 x CF2/CF3 groups) in the surfactant additives. There are numerous applications of LSEMs today, such as printing, painting, adhesion, metal-plating, emulsification/suspension (medical, cosmetic, food packaging, etc.), washing (electronics, clothes, etc), antifogging and repellent surfaces (self-cleaning windows, water-proof textiles, anti-snow, anti-fog surfaces, papers, fibers, etc.). Therefore, development and optimization of LSEMs has attracted much attention, and a wide variety of useful LSEMs can be obtained by Fluorinating surfaces. Unfortunately, this has dramatic environmental consequences because of the persistence and bioaccumulation of Fluorocarbons (FCs). [Food Addit Contam. 2005, 10, 1023-31, Environ. Sci. Technol. 2006, 40, 32-44]. As outlined below, this project is centred on intelligent programmed molecular design of hydrocarbon (HC) surfactants, which will generate similar surface properties to the undesirable FCs.
