    • Optical fibre comprising a glass portion and at least one coating of crosslinked polymer material surrounding said glass portion, said coating being obtained by crosslinking a mixture comprising: at least one crosslinkable liquid composition comprising at least one oligomer containing at least one reactive functional group, at least one diluent monomer capable of reacting with said reactive functional group and at least one photo-initiator; at least one inorganic material with lamellar structure formed by a plurality of lamellae that have been surface-treated beforehand with a compatibilizer; characterized in that said coating is formed by said crosslinked liquid composition intercalated between the lamellae of said inorganic material. Preferably, said coating is a secondary coating or, in the case of a ribbon of optical fibres, it is a common polymer coating known as a "common coating".
    • 包含玻璃部分和围绕所述玻璃部分的交联聚合物材料的至少一层涂层的光纤,所述涂层通过交联混合物获得,所述混合物包含:至少一种包含至少一种含有至少一个反应性官能团的低聚物的可交联液体组合物, 至少一种能够与所述反应性官能团和至少一个光引发剂反应的稀释剂单体; 至少一种具有层状结构的无机材料,由已经用增容剂预先表面处理的多个薄片形成; 其特征在于,所述涂层由插入在所述无机材料的薄片之间的所述交联液体组合物形成。 优选地,所述涂层是二次涂​​层,或者在光纤带的情况下,它是被称为“普通涂层”的普通聚合物涂层。
