综述了聚合物直接氟化的基本特点和工业应用。介绍了聚苯乙烯、聚对苯二甲酸乙二酯、聚(2，6-二甲基-1，4-苯氧基)、PMMA、LDPE(两种类型)、HDPE(六种类型)、聚乙烯三甲基硅烷、聚4-甲基戊烯-1、聚酰亚胺基质5216(R)、聚砜、聚醚醚酮、聚碳酸酯硅氧烷、聚砜-聚丁二烯嵌段共聚物、聚丙烯、PVF、PVDF等一系列聚合物直接氟化的基本特征。研究了氟化混合物(F-2-He-N-2-O-2-HF)的组成、氟分压、温度和氟化时间对氟化层的形成速度和氟化层的化学成分、密度、折射率、表面能、气体分离性质和摩擦系数的影响。研究了长寿命和短寿命自由基的形成和终止以及丙烯腈接枝到氟化聚合物上的过程。综述了直接氟化在提高聚合物产品商业性能方面的工业应用，如用于气体分离的聚合物膜的分离系数、聚合物容器、管道和包装的阻隔性能、粘附性、印刷性、润湿性和可见光和红外的透明度。(C)2005 Elsevier B.V.保留所有权利。
Fundamental features and industrial applications of the direct fluorination of polymers are reviewed. Fundamental features of the direct fluorination of a set of polymers, such as polystyrene, polyethyleneterephthalate, poly(2,6-dimethyl-1,4-phenylene oxide), PMMA, LDPE (two types), HDPE (six types), polyvinyltrimethylsilane, poly(4-methyl-pentene-1), polyimide Matrimid 5216 (R), polysulfones, polyetheretherketone, polycarbonatesiloxane, polysulphone-polybuthadiene block-copolymers, polypropylene, PVF, PVDF, etc. are described. Influence of composition of the fluorinating mixture (F-2-He-N-2-O-2-HF), fluorine partial pressure, temperature and fluorination duration, on the rate of formation of the fluorinated layer and the chemical composition, density, refraction index, surface energy, gas separation properties and friction coefficient of fluorinated layer have been investigated. Processes of formation and termination of long-living and short-living radicals and grafting of acrylonitrile to fluorinated polymers have been studied. Industrial applications of the direct fluorination to enhance the commercial properties of polymeric goods, such as separation factor of polymeric membranes for gas separation, barrier properties of polymer vessels, pipes and packagings, adhesion, printability, wetting and transparency in visible and IR are reviewed.
