PLASMA TREATMENT OF KEVLAR AND NOMEX

摘要

The influence of plasma treatment of Kevlar and Nomex fibers is discussed. Kevlar and Nomex fibers were exposed to plasma for different time ranges up to five minutes. Samples of fibers were treated in the plasma source of diffuse coplanar surface barrier discharge. The air was an operational gas. The structure and the appearance of Kevlar and Nomex fibers are observed by mean scanning electron microscopy. The alternative method to value fibre surface is infrared spectroscopy. For this analysis we used attenuated total reflectance Fourier transform infrared spectroscopy. To detect changes in chemical composition of the fiber surface was performed by X-ray photoelectron spectroscopy analysis.
