| Outline of Final Research Achievements |
Hydrogen atoms (H) were generated from hydrogen gas (H2) by using a homemade H atom generator consisted of an ultraviolet light source incorporating a deuterium lamp and a reaction tube made of polycarbonate, under atmospheric pressure conditions. In order to confirm the generation of hydrogen atoms, resulting hydrogen atoms were irradiated onto the surface of a tip of polytetrafluoroethylene and a reaction product hydrogen fluoride (HF) were detected by an atmospheric pressure corona discharge ionization mass spectrometer. In order to examine the influence of hydrogen atoms on the resistance and degradation characteristics of an aramide synthetic polymer, Kevlar, the hydrogen atoms were irradiated to Kevler fibers. However, any degradation products were not detected, because the hydrogen-bond networks of Kevlar protect the carbonyl oxygens from the attack of hydrogen atoms.
