Abstract
Description
この構成により、基材の材質に影響されることなく抗菌作用を有する銅被膜が形成されるとともに、長期間に渡って抗菌作用を持続させることができる。
R=Ut-At
なお、Rは、抗菌活性値を示し、Utは、無加工試験片における24時間培養後の生菌数の対数値の平均値であり、Atは、抗菌加工試験片における24時間培養後の生菌数の対数値の平均値である。
0:肉眼及び実体顕微鏡下でかびの発育が認められない
1:肉眼では、かびの発育が認められないが、実体顕微鏡下では明らかに確認できる。
2:肉眼で、かびの発育が認められ、発育部分の面積は試料の全面積の25%未満
3:肉眼で、かびの発育が認められ、発育部分の面積は試料の全面積の25%以上50%未満
4:菌糸はよく発育し、発育部分の面積は試料の全面積の50%以上
5:菌糸の発育は激しく、試料全面を覆っている
11…銅被膜
12…保護膜
