Optical fibers are coated with a clay-polymer nanocomposite composition comprising optionally a hydrophobic layered silicate dispersed in a radiation curable resin preferably on a molecular level. The radiation curable resin may contain a mixture of a radiation curable oligomer and a diluent(s). The coating when cured has improved tensile properties, and when used as an outer primary coating exhibits low microbending sensitivity.
光纤表面涂有粘土聚合物纳米复合材料,该复合材料可选地包括分散在辐射固化
树脂中的疏
水性层状
硅酸盐,最好是分子级的。辐射固化
树脂可包含辐射固化低聚物和稀释剂的混合物。固化后的涂层具有更好的拉伸性能,用作外层主涂层时具有较低的微弯曲敏感性。
