Description

一种聚合物荧光多彩纤维的制备方法 A method for preparing a fluorescent polymer fibers colorful

技术领域 FIELD

[0001] 本发明属于荧光纤维的制备领域。 [0001] The present invention belongs to the field of preparing the fluorescent fibers. 硒化镉(CdSe)具有良好的光学特点和稳定性, 在发光器件、光学生物标记等领域有广泛的应用前景,本发明通过甲苯分散包覆到聚苯乙烯(PQ纤维中,获得了呈现对应量子点荧光特性的多彩纤维。 Cadmium selenide (CdSe) having good optical characteristics and stability, a wide range of potential applications in the field of light emitting devices, optical and other biomarkers, the present invention is coated onto a polystyrene dispersion (PQ fibers by toluene to give the corresponding presentation colorful fiber quantum dot fluorescent properties.

背景技术. Background technique.

[0002] 随着科学技术的进步,新的荧光纤维不断涌现,它在.、光敏变色材料、.荧光装饰材料、.光记录材料、储光纤维、光纤维、防伪纤维、光纤等多个领域有着广泛的应用。 [0002] With the progress of science and technology, a new fluorescent fibers emerging, it., Photochromic materials, fluorescent decorative material. FIELD plurality of optical recording materials, the optical fiber storage, optical fibers, security fibers, optical fiber, It has a wide range of applications. 量子点由于量子力学的奇妙规则而具有显著的尺寸效应,基本上高于特定域值的光都可吸收, 而一个有机染料分子只有在吸收合适能量的光子后才能从基态升到较高的激发态,所用的光必须是精确的波长或颜色,这明显与半导体体相材料不同,而量子点要吸收所有高于其带隙能量的光子,但所发射的光波长(即颜色)又非常具有尺寸依赖性。 Since the quantum dot wonderful rules of quantum mechanics has significant size effect, substantially higher than a certain threshold of light can be absorbed and an organic dye molecules suitable only after photon absorption to rise to a higher energy excited from the ground state state, light used must be precise wavelength or color, which is obviously the semiconductor body with different materials, and quantum dots to absorb all higher than the band gap energy photons, but the light wavelength (i.e. color) of the emitted and very size-dependent. 所以,单一种类的纳米半导体材料就能够按尺寸变化产生一个发光波长不同的、颜色分明的标记物家族,这是染料分子根本无法实现的。 Therefore, a single species of nano-semiconductor materials can generate a different emission wavelength, color family distinct markers by dimensional change, which is impossible to achieve a dye molecule. 与传统的染料分子相比,量子点确实具有多种优势。 Compared with the traditional dye molecules, quantum dots does have a number of advantages. 无机微晶能够承受多次的激发和光发射,而有机分子却会分解.持久的稳定性可以让研究人员更长时间地观测细胞和组织,并毫无困难地进行界面修饰连接。 Inorganic ceramics can withstand multiple excitation and emission of light, but it will decompose organic molecules. Lasting stability allows researchers more time to observe cells and tissues, and without any difficulty connecting interface modification. 量于点最大的好处是有丰富的颜色。 The maximum amount of benefit point there is a wealth of color. 生物体系的复杂性经常需要同时观察几种组分,如果用染料分子染色,则需要不同波长的光来激发,而量于点则不存在这个问题,使用不同大小(进而不同色彩)的纳米晶体来标记不同的生物分子。 Complexity of biological systems often need to observe several components, if dyed with a dye molecule, it is necessary to excite light of different wavelengths, and the amount at this point is not an issue, the use of different sizes (and thus different colors) nanocrystals to mark different biological molecules. 使用单一光源就可以使不同的颗粒能够被即时监控。 A single light source can make use of different particles can be real-time monitoring. 量子点特殊的光学性质使得它在生物化学、分子生物学、细胞生物学、蛋白质组学、药物筛选、生物大分子相互作用等研究中有极大的应用前景。 Special optical properties of quantum dots so that it has great applications in biochemistry, molecular biology, cell biology, proteomics, drug screening, and the like interactions of biological macromolecules. 但由于量子点的毒性和荧光不稳定性,使其难于使用,对量子点进行包覆是一种理想的手段。 However, due to the toxicity and instability of quantum dots, it is difficult to use, to be coated quantum dots is an ideal means. 因其由于表面效应等原因使得量子点难以均勻的分散在聚合物溶液中形成纺丝液,不能采用静电纺丝技术制备荧光纤维。 Effect, etc. due to its surface such that the quantum dot is difficult to uniformly dope the dispersion is formed in the polymer solution can not be prepared by electrospinning fluorescent fibers. 目前CdS量子点是以原位生成的办法包覆在水溶聚合物制成荧光纤维的.。 Currently CdS quantum dots is generated in situ approach coated water soluble polymer is made of fluorescent fibers ..
