With the advances in science and engineering in the second part of the 20th century, emerging plasma-based technologies continuously find increasing applications in the domain of polymer chemistry, among others. Plasma technologies are predominantly used in two different ways: for the treatment of polymer substrates by a reactive or inert gas aiming at a specific surface functionalization or for the synthesis of a plasma polymer with a unique set of properties from an organic or mixed organic-inorganic precursor. Plasma polymer films (PPFs), often deposited by plasma-enhanced chemical vapor deposition (PECVD), currently attract a great deal of attention. Such films are widely used in various fields for the coating of solid substrates, including membranes, semiconductors, metals, textiles, and polymers, because of a combination of interesting properties such as excellent adhesion, highly cross-linked structures, and the possibility of tuning properties by simply varying the precursor and/or the synthesis parameters. Among the many appealing features of plasma-synthesized and -treated polymers, a highly reactive surface, rich in free radicals arising from deposition/treatment specifics, offers a particular advantage. When handled carefully, these reactive free radicals open doors to the controllable surface functionalization of materials without affecting their bulk properties. The goal of this review is to illustrate the increasing application of plasma-based technologies for tuning the surface properties of polymers, principally through free-radical chemistry.
随着 20 世纪后半叶科学和工程的进步，新兴的等离子体技术不断在聚合物化学等领域得到越来越多的应用。等离子体技术主要有两种不同的应用方式：一种是用反应性或惰性气体处理聚合物基底，以实现特定的表面功能化；另一种是用有机或有机-无机混合前体制备具有独特性能的等离子体聚合物。等离子体聚合物薄膜（PPF）通常通过等离子体增强化学气相沉积（PECVD）沉积，目前引起了极大的关注。由于具有良好的附着力、高度交联的结构以及通过简单改变前体和/或合成参数来调整性能的可能性等有趣特性，此类薄膜广泛应用于各种领域的固体基底涂层，包括膜、半导体、金属、纺织品和聚合物。在等离子体制备和处理聚合物的众多吸引人的特性中，表面高度反应性、富含沉积/处理特异性产生的自由基是一个特别的优势。如果处理得当，这些反应性自由基可以在不影响材料本体性质的情况下，为可控的材料表面功能化开辟道路。本文的目的是通过自由基化学，举例说明等离子体技术在调节聚合物表面性质方面的应用日益广泛。
