| Outline of Final Research Achievements |
As a method of visualizing degradation behavior occurring when wood is used as an exterior material with the passage of time at the cell level without influence of artifact, the advantage of low vacuum scanning electron microscope (LVSEM) without coating sample Focusing attention, the optimum observation condition was established and the following results were obtained.
We conducted outdoor exposure and accelerated weather resistance test and succeeded in visualizing the occurrence behavior of steric deterioration over time at the cell level. In addition, the degradation behavior of phenolic resin, silicone rubber emulsion, treated with copper / azole type preservative, and treated with polymerizable ionic liquid was visualized.
Species used are Cryptomeria japonica, Liliodendron turipifera, Alnus japonica, Melia azedarach, Toona sinensis, Choreopondias axillaris, Firmiana simplex.
