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.

低表面能材料（lsem）是通过将表面层附着在衬底上而获得的。表面能低的原因是界面层的潜在化学结构：控制表面性质的能力是化学结构的直接结果。自抗润湿表面首次开发以来，一直有必要在表面活性剂添加剂中使用长氟化尾（bbb7 × CF2/CF3基团）。如今，lsem有许多应用，例如印刷，绘画，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，服装等），防雾和驱避表面（自清洁窗户，防水纺织品，防雪，防雾表面，纸张，纤维等）。因此，对表面氟化制备的lsem的开发和优化备受关注，通过氟化表面可以获得各种各样的有用的lsem。不幸的是，由于氟碳的持久性和生物积累，这对环境造成了严重后果。食品添加剂控制，2005,10,1023-31，环境。科学。技术，2006,40,32-44]。如下所述，该项目以碳氢化合物（HC）表面活性剂的智能编程分子设计为中心，该表面活性剂将产生与不需要的碳氢化合物相似的表面特性。
