| Material is made from a large number of sizes of 20 ~ 30nm particles deposited by pearl chain through mutual cross-linking and entanglement to form three-dimensional network structure. In the string of pearls with a large number of holes between the stacked structure, the existence of holes can be estimated from the figure, mainly in the size of 20nm below, but there are a few holes of about 50nm or 100nm. |
