| 專利名稱 | Diffusion beads with core-shell structure | | 專利證號 | US7563508B2 | | 國別 | 美國 | | 獲證日期 | 2009-07-21 | | 專利摘要 | The diffusion beads according to the present invention have a core-shell structure of multi-layered beads consisting of organic and inorganic materials. The diffusion beads are used for improving functions of conventional organic and inorganic polymer diffusion beads. The structure according to the present invention no only enhances light scattering characteristics of the diffusion beads, but also strengthens the thermal stability and geometric stability thereof. | IPC國際分類號 | B32B000516 | G02B000502 | G02F00011333 |
