INFLUENCE OF CO2 LASER RADIATION ON THE SURFACE PROPERTIES OF POLY(ETHER ETHER KETONE)

摘要

The influence of CO2 laser radiation on the surface properties of poly( ether ether ketone) (PEEK) is shown. The influence on the surface chemistry is nearly negligible, but the roughness increases and the crystallinity in the surface region decreases with increasing laser intensity. The crystallinity of the surface region was determined by a newly developed procedure using photoacoustic infrared spectroscopy. (C) 1997 John Wiley & Sons, Inc. [References: 13]
