Description

新型纳米二氧化钛基复合纤维
技术领域
本发明涉及一种新型纳米二氧化钛基复合纤维,属于化工材料技术领域。
背景技术
纳米二氧化钛是白色疏松粉末,屏蔽紫外线作用强,有良好的分散性和耐候性。可用于化妆品、功能纤维、塑料、涂料、油漆等领域,作为紫外线屏蔽剂,防止紫外线的侵害。也可用于高档汽车面漆,具有随角异色效应。
纳米级二氧化钛,亦称钛白粉。直径在100纳米以下,产品外观为白色疏松粉末。具有抗线、抗菌、自洁净、抗老化性能,可用于化妆品、功能纤维、塑料、油墨、涂料、油漆、精细陶瓷等领域。
纳米二氧化钛主要有两种结晶形态:锐钛型(Anatase)和金红石型(Rutile)。金红石型二氧化钛比锐钛型二氧化钛稳定而致密,有较高的硬度、密度、介电常数及折射率,其遮盖力和着色力也较高。而锐钛型二氧化钛在可见光短波部分的反射率比金红石型二氧化钛高,带蓝色色调,并且对紫外线的吸收能力比金红石型低,光催化活性比金红石型高。在一定条件下,锐钛型二氧化钛可转化为金红石型二氧化钛。
纳米纤维是指直径处在纳米尺度范围(1~100nm)内的纤维,根据其组成成分可分为聚合物纳米纤维、无机纳米纤维及有机/无机复合纳米纤维。纳米纤维具有孔隙率高、比表面积大、长径比大、表面能和活性高、纤维精细程度和均一性高等特点,同时纳米纤维还具有纳米材料的一些特殊性质,如由量子尺寸效应和宏观量子隧道效应带来的特殊的电学、磁学、光学性质。纳米纤维主要应用在分离和过滤、生物及医学治疗、电池材料、聚合物增强、电子和光学设备和酶及催化作用等方面。
随着纳米纤维材料在各领域应用技术的不断发展,纳米纤维的制备技术也得到了进一步开发与创新。到目前为止,纳米纤维的制备方法主要包括化学法、相分离法、自组装法和纺丝加工法等。而纺丝加工法被认为是规模化制备高聚物纳米纤维最有前景的方法,主要包括静电纺丝法、双组份复合纺丝法、熔喷法和激光拉伸法等。
国内在纳米二氧化钛基复合纤维研究方面历史较短, 材料研究基本上处于探索阶段。
