| 摘 要： | 低温等离子体表面改质技术,近年来在纤维加工领域的应用引起广泛注目。纤维、高分子材料经低温等离子体处理,在纤维基质中生成自由基。这些自由基同活性原子团一样,其中不稳定的自由基迅速重新结合,而稳定的自由基就残留在纤维基质中。本文研究了天然纤维棉、麻、羊毛和蚕丝分别在O_2、N_2、Ar、CO及CF_4气体中的低温等离子体表面改质处理,用ESR光谱测定了纤维基质中生成的自由基的相对强度,并讨论了热处理对自由基稳定性的影响。

| Abstract: | Natural fibers such as cotton, linen, wool and silk were treated with low-temperature-plasmas of O_2, N_2, Ar, CO, and CF_4. The relative free-radical intensity of the plasma-treated fibers was measured by means of ESR spectroscopy. The free radicals in the fibers treated in the plalmas increased in the following order: cotton(?)lincn>wool(?)silk, CF_4>CO>Ar>N_2>O_2. |

| Keywords: | ESR study Low temperature plasma Fiber substrate Relative free-radical intensity |
