Název v původním jazyce

Ion-Beam Induced Chemical and Structural Modification in Polymers

Popis výsledku v původním jazyce

In order to increase the sensitivity to moisture uptake of polyimide (PI) and polyethersulforre films applied in bimorphic humidity sensors 50, 130 and 180 keV boron ions with irradiation doses between 10(13) and 10(16) B+/cm(2) were implanted. A complexinvestigation of the following features has been carried out: chemical changes in the surface regions by attenuated total reflection-FFIR spectroscopy, Raman spectroscopy and X-ray photoelectron spectroscopy (XPS); optical properties by spectroscopic ellipsometry; hardness and elastic modulus by depth-sensing low-load indentation technique; conductivity of modified polymer films. It could be shown, that the partial destruction of chemical bonding under ion bombardment leads to the creation of new amorphous and graphite-like structures, which increase the surface film conductivity by several orders of magnitude, and enhances the sensitivity of these polymer films to moisture uptake
