【摘要】：针对太赫兹聚合物光子晶体光纤的应用需求,对聚合物光纤的制备材料、预制棒制备、拉伸工艺等关键制备工艺进行了研究.分析了聚合物材料的特性,并进行实验验证,结果表明ZEONEX材料的吸收系数低于3cm~(-1),吸水性低于0.01%,玻璃化转变温度和分解温度分别高达136℃和420℃,在太赫兹光纤制备中具有优良性能.预制棒制备和光纤拉伸的工艺方面,在注塑法的基础上改进了模具系统,使用可控的微压拉丝技术,在10200Pa范围内可实现±1.5Pa的微压差精确控制,较大程度上提高了光纤预制棒的成品率和光纤的形变控制,有望制备出高空气填充率的聚合物光子晶体光纤.
[Abstract]:In order to meet the requirements of the application of terahertz photonic crystal fiber (PCF), the preparation of polymer fiber, the preparation of prefabricated rods, and the stretching process were studied. The properties of polymer materials were analyzed and verified by experiments. The results show that the absorption coefficient of ZEONEX is lower than 3 cm ~ (-1), the water absorption is lower than 0.01 and the glass transition temperature and decomposition temperature are as high as 136 鈩，
