虽然该协议中列出的许多步骤对于薄膜传输的成功至关重要,但定制设计的 3D 打印排放室的性质允许根据用户的具体要求实现广泛的灵活性。例如,如果接收器基板的直径大于本研究中使用的 25 mm 直径 AAO 盘,则可以对排放室进行适当修改以适应新的规格。但是,协议的某些方面对于确保有效的传输结果是必要的。
为转移工具和排放室选择 3D 打印材料对于该协议的成功非常重要?...

薄膜和纳米膜器件最近引起了广泛的兴趣,因为它们有可能用于广泛的应用,包括柔性光伏和光子、可折叠显示器和可穿戴电子产品1。2,3.制造这些各类装置的一项要求是将薄膜转移到任意基板的表面,由于这些薄膜的脆弱性和宏观缺陷的频繁生产,这仍然具有挑战性结构,如皱纹,裂缝,和眼泪,在薄膜内转移后转移4,5,6,7。手工手移、钳子和线环是薄膜转移的常用方法,但不可避免地会导致结构不协调、塑性变形8、9。已经探索了各种类型的薄膜转移方法,例如:1) 聚二甲基硅氧烷 (PDMS) 邮票转移,这涉及使用弹性邮票从供体基质获得薄膜,然后转移到接收基板10和2)牺牲层转移11,其中蚀刻剂用于选择性地溶解支撑基板和薄膜之间的牺牲层,从而解除薄膜。然而,这些技术本身并不一定允许薄膜转移,而不会对薄膜12内造成损伤或缺陷形成。
在这里,我们展示了一种基于牺牲层提升和半月板引导转移的新型、低成本和通用的易感方法,采用定制设计的 3D 打印排放室系统,以机械方式将块共聚物 (BCP) 薄膜放置在多孔基板的中心,如阳极氧化铝(AAO)盘,具有很少到无的宏观缺陷结构,如皱纹、撕裂和裂纹。在目前的情况下,这些转移的薄膜然后可用作设备在水过滤研究,有可能在顺序渗透合成(SIS)处理9。从光学显微镜获得的转移膜的图像分析表明,半月板引导的漏室系统提供平滑、坚固和无皱的样品。此外,这些图像还展示了系统能够可靠地将薄膜膜放置在接收基板的中心。我们的结果对需要将薄膜结构转移到任意多孔基板表面的任何类型的器件应用都有着重要影响。

procedure for the transfer of polymer films onto porous substrates with minimized defects

制造含有薄膜复合膜的装置需要将这些薄膜转移到任意支撑基板的表面。以高度可控、机械化和可重复的方式完成此传输,可以消除在薄膜内产生影响器件性能和可用区域的宏观缺陷结构(例如,撕裂、裂纹和皱纹)每个样品。在这里,我们描述了一个高度控制和机械化地将聚合物薄膜转移到任意多孔支撑基板上的通用协议,以便最终用作水过滤膜装置。具体来说,我们在牺牲性水溶性聚(丙烯酸)层和硅晶片基板之上制造块共聚物(BCP)薄膜。然后,我们使用定制设计的 3D 打印传输工具和排放室系统将 BCP 薄膜沉积、提升并将薄膜转移到多孔阳极氧化铝 (AAO) 支撑盘的中心。由于水和 3D 打印塑料排水室之间形成的半月板的引导,可显示转移的 BCP 薄膜始终放置在支撑表面的中心。我们还将我们的机械化转移处理薄膜与手工转让的薄膜与使用钳子进行比较。从机械化工艺中转移的薄膜的光学检测和图像分析证实,与手动产生的大量眼泪和皱纹相比,几乎不产生大尺度不均匀或塑性变形用手转移。我们的结果表明,与许多系统和应用中的其他方法相比,提出的薄膜转移策略可以减少缺陷。

BCP膜样品是按照前面描述的程序9制造的。样品被放置在3D打印传输工具的加载臂的唇上(图1,左),然后用实验室千斤顶将样品降低到3D打印的排水室工具的入口坡道上(图1,右图)。BCP膜与底层供体硅基板之间的聚酸(PAA)牺牲层溶解在排水室内的水中,形成浮乙基膜。然后,操作注射器泵(图2,底部)...

Procedure for the Transfer of Polymer Films Onto Porous Substrates with Minimized Defects

我们提出了一种使用 3D 打印排放室将块共聚物薄膜转移到多孔支撑基板上的高度受控和无皱程序。排水室设计与涉及将大分子薄膜转移到多孔基板上的所有程序具有一般相关性,通常以不可重复的方式手工完成。

为了研究膜应用中的聚合物薄膜，材料必须从抛光、光滑的基材转移到多孔基材，其方式不会折叠、皱褶、撕裂或塑性变形薄膜。本视频描述了一个 3D 可打印排空室，旨在实现这一目标，并关注此处显示的工艺流程中的四至六个步骤。本工作中使用的样品由硅晶片基板组成，其中旋转涂层一叠水溶性聚丙烯酸，然后是随机共聚聚合物垫和聚苯乙烯块聚甲基甲基丙烯酸酯块共聚物胶质。步骤四至六的目的是将这种孔形成块共聚合物从硅晶片转移到多孔阳极氧化铝膜上，以便随后转换为功能过滤装置。排水室由顶部斜坡组成，可引入聚合物薄膜堆栈，底部可容纳多孔基板和去压水。顶部部分从 PLA 从灯丝打印机打印，底部从喷墨 3D 打印机打印。使用灯丝打印机还从 PLA 打印样品传输工具。第一部分连接到实验室插孔，以便样品可以平稳地升起和降低，并且不会因手部运动而产生振动。第二部分将 BCP 晶圆片保持到位。这样，传输过程就可以开始了。首先，组装 BCP 工具。夹紧部分是螺纹的，因此螺钉可以固定到实验室插孔。然后，使用钳子将阳极氧化氧化铝基板放置在排放室的底部。接下来，插入橡胶 O 环以确保防水密封。排放室的斜坡部分紧紧拧紧。最后，透明乙烯基管连接到排水室底部的喷口，另一端连接到注射器泵内部的注射器，以便能够控制排水速率。接下来，将带聚合物堆栈的硅晶片放置在转移工具上，排放室也充满去电化水。硅晶片然后慢慢降低到水中，导致聚丙烯酸层开始溶解。这种溶解使硅晶片中的聚合物薄膜脱光，使其漂浮在水面上。下一步拆下转移工具，通过启动注射器泵激活排水。水通过氧化铝基板吸出，然后泵从腔室中抽出。此处显示的排水速度为每分钟 1 毫升。斜坡的角度和腔室的设计将聚合物薄膜指向气缸的中心。在这里，膜和水位已达到设备的圆柱体，创造了一个更突出的半月板，它保持膜紧绷和居中，因为它低于底层，阳极氧化铝膜。一旦水被排干，聚合物与膜接触，可以拧开腔室，使剩余的水蒸发。整个过程，包括设置和排水，大约需要15分钟，但这次可以通过提高排水速率和通过建造需要更小的体积的室内来缩短。此处显示的是使用多孔膜直接从水浴表面挖出的薄膜。膜的撕裂和位置的中心是显而易见的。对于各种放置的膜，膜中心到基板中心的距离显示在右侧。在这里，我们看到利用排放室的可重复性改进。完好无损的薄膜是明显的，膜中心到基板中心的距离被显示最小化。排水室减少了在手动方法上撕裂和折叠薄膜的机会。清洁的实验室环境没有灰尘，将限制附带的污染。这种薄膜膜转移方法明确减少了对薄膜的损害，并提高了其放置在基材上的精度和可重复性。通过手动去除在水面上操纵薄膜的艰巨任务，对基本排水室设计的修改可以实现不同的聚合物样品尺寸和多孔基板类型。
