Description

纳米粒子制备装置
【技术领域】
本发明涉及一种纳米粒子制备装置，尤其是利用激光消熔法的纳米粒子制备装置。
【背景技术】
由于纳米粒子的表面效应和体积效应，其具有特殊的化学反应性与光学性质等物理特性，可应用于催化剂、生物分子感测、光触媒、高导热的纳米流体等领域。
现有技术中，激光消熔法是制备纳米粒子的方法之一。其将高纯度的块材置于容器中，用含有适量稳定剂的保护溶液浸没容器中的块材，利用聚焦的高能激光束打在块材表面上，以消熔块材而产生分子团簇，并通过保护溶液所提供的低温环境及稳定剂分散所生成的纳米粒子。保护溶液中的稳定剂如各种界面活性剂，可附着于纳米粒子表面产生静电排斥力，使纳米粒子难以凝聚为大颗粒而沉降，从而获得均匀分散的纳米粒子溶液；颗粒的大小可以由界面活性剂的种类、浓度、激光功率的大小、激光波长等参数来控制。但是，现有的激光消熔法纳米粒子制备装置是静置的，在制备完成后，需待收集生成溶液完毕，才可再置入新保护溶液，进行制备，上述两个步骤不能同时进行，较为不便，不利于连续式的大量生产。
有鉴于此，有必要提供一种纳米粒子制备装置，其可具有连续制备纳米粒子等特点。
【发明内容】
下面将以若干实施例说明一种连续制备纳米粒子的装置，其可实现纳米粒子的连续式生产。
为实现以上内容，提供一种纳米粒子制备装置，该制备装置包括:
一容器，该容器设有进液口及出液口；
一靶材，设于所述容器的底部；
一激光装置，用于提供一激光束，以轰击该靶材；
所述进液口位置高于靶材。
优选的，该容器底部还设置一超声波装置。
所述靶材的材质可选用碳材、金属或其合金。
所述激光装置可选用气体激光器、液体激光器、固体激光器或半导体激光器。
相对于现有技术，本技术方案所提供的纳米粒子制备装置，其容器上设有进液口与出液口，在制备过程中，生成的纳米粒子可随保护溶液从出液口连续流出，并可在进液口连续供给保护溶液，从而实现纳米粒子的连续制备，生产效率高，便于连续式大量生产。
【附图说明】
图1是本发明第一实施例的纳米粒子制备装置示意图。
图2是本发明第二实施例设有超声波装置的纳米粒子制备装置示意图。
图3是利用本发明所提供装置进行纳米粒子制备的示意图。
【具体实施方式】
下面结合附图将对本发明实施例作进一步的详细说明。
参见图1，本发明第一实施例提供的纳米粒子制备装置100，其包括一容器10，一靶材20及一激光装置30。
所述容器10，其设有:一进液口11，及一出液口12。该容器10可用于盛装一保护溶液。进液口11可用于连续供给保护溶液，其位置设置高于靶材20上表面；出液口12可用于收集制备得到的含有纳米粒子的溶液，其设置于容器10的侧壁。通过进液口及出液口的设置，可使纳米粒子的制备与收集同步进行。
所述靶材20，设于容器10的底部，该靶材20具有一上表面，其材料可根据所需纳米粒子种类进行选择，可选用碳材、金属或其合金。
所述激光装置30，用于提供一激光束，经由所述上表面轰击靶材20。该激光装置30可选用气体激光器、液体激光器、固体激光器或半导体激光器。
参见图2，本发明第二实施例为使制备得到的纳米粒子更均匀的分布于保护溶液中，还可在容器10底部设置一超声波装置40。
结合图3，对本发明实施例提供的纳米粒子制备装置的操作过程做详细描述:
制备纳米粒子时，为更便于溶液置入及收集，可将容器10相对于水平面倾斜一角度θ，该倾斜角θ满足0°≤θ≤60°。
(1)将靶材20置于容器10底部，本实施例中选用铜靶；
(2)将一保护溶液装入容器10中，并将铜靶20完全浸没。该保护溶液可选用聚乙烯醇、壬基酚聚氧乙烯醚、烷基酚聚氧乙烯醚、十二烷基硫酸钠等之水溶液，本实施例中选用聚乙烯醇水溶液；
(3)打开激光装置30，利用激光束轰击铜靶20，本实施例中选取固体激光器；
(4)打开超声波装置40，所产生的纳米粒子在超声波作用下，均匀分散于保护溶液中而得含纳米粒子的溶液；
(5)待保护溶液中纳米粒子达到预定浓度时，打开出液口12上的阀门(图未标示)，收集含有纳米粒子的溶液，并通过进液口供给保护溶液，控制进液口11处保护溶液的流速以及出液口12处纳米粒子溶液的流出速度，使容器10中溶液的液位基本保持不变，从而实现纳米粒子的连续制备。
本实施方式提供的纳米粒子制备装置，其容器上设有进液口与出液口，制备过程中可使生成的纳米粒子随保护溶液从出液口连续流出，并可在进液口连续供给保护溶液，从而实现纳米粒子的连续制备，生产效率高，便于连续式大量生产。
另外，本领域技术人员还可在本发明精神内做其它变化，如适当变更超声波装置的设置位置，或变更容器与基底夹角的大小，或变更靶材的材料，或变更激光装置的类型，或变更进液口或出液口的个数、位置等，只要其不偏离本发明的技术效果均可。这些依据本发明精神所做的变化，都应包含在本发明所要求保护的范围之内。
