Abstract
Polymer films, deposited from acetylene and argon plasma mixtures, were bombarded with 150 keV He + ions, varying the fluence, Φ, from 10 18 to 10 21 ions/m 2. Molecular structure and optical gap of the samples were investigated by infrared and ultraviolet–visible spectroscopies, respectively. Two-point probe was employed to determine the electrical resistivity while hardness was measured by nanoindentation technique. It was verified modification of the molecular structure and composition of the films. There was loss of H and increment in the concentration of unsaturated carbon bonds with Φ. Optical gap and electrical resistivity decreased while hardness increased with Φ. Interpretation of these results is proposed in terms of chain crosslinking and unsaturation.
