摘要

低温等离子体技术是一种清洁且高效节能的新型材料表面改性技术.该技术在改善材料表面性能的同时,仍可保持本体性能的特色,在材料表面改性方面具有广阔的应用前景.然而,经过低温等离子体处理的聚合物材料的改性效果会随时间发生明显衰减,改性效果存在时效性.概述了时效性的产生机制、表征方法以及克服时效性的方法,重点讨论了聚合物的结构、等离子体处理工艺参数,包括等离子体工作气氛、处理时间、处理功率、放置环境等因素对时效性的影响.%Low temperature plasma, as a novel surface modification technology, is characterized by clean, high efficiency and energy-saving. Plasma treatment can improve the surface properties of polymer materials without affecting their bulk features, which impart itself a potentially abroad application in the field of surface modification. However, the plasma-improved surface properties usually decay with time,known as ageing effect of plasma treatment. The mechanism and characterization methods of ageing effect as well as approaches to overcome ageing effect were briefly reviewed. The influences of polymer structure, plasma treatment parameters, such as gas, treating time and power, and storage environment on ageing behavior were especially discussed.
