| Sumario: | The light-induced modification of mechanical and optical properties of several amino-
styrene-containing polymers has been investigated. The nano- and microindentation techniques were used for determination of mechanical parameters. The variable-energy positron
annihilation spectroscopy (slow-positron beam technique) was developed to measure defect
depth profiles in the near-surface region. The increase of S-parameter with the increasing of
nanohardness and elastic modulus were determined for these materials. |
