在本文中，我们介绍了一种简单而强大的策略，用于键合聚（二甲基硅氧烷）（PDMS）与各种热塑性基板，以制造基于热塑性塑料的封闭微流控器件，并检查使用所提出的方法实现塑料-塑料键合的可行性。所提出的键合策略是通过首先在氧化的热塑性表面上涂覆胺官能团来实现的。接下来，胺官能化的表面与低分子量PDMS的单层反应，通过形成坚固的胺-环氧键，用环氧官能团封端。然后将PDMS涂覆的热塑性塑料和PDMS氧化并在25 °C下在0.1 MPa的压力下永久组装15分钟，从而在微通道的所有四个内壁上产生PDMS样表面。进行了表面表征，包括水接触角测量，X射线光电子能谱（XPS），和荧光测量，以确认在塑料表面上的薄PDMS层的成功涂层，并通过进行剥离测试，爆裂测试，和泄漏测试的结合强度进行了分析。使用所提出的方法，我们可以成功地键合各种热塑性塑料，如聚（甲基丙烯酸甲酯）（PMMA），聚碳酸酯（PC），聚苯乙烯（PS），和聚（对苯二甲酸乙二醇酯）（PET）与聚二甲基硅氧烷没有崩溃或变形的微通道，所提出的方法被成功地扩展到两种热塑性塑料，PMMA和PC的键合。
In this paper, we introduce a simple and robust strategy for bonding poly(dimethylsiloxane) (PDMS) with various thermoplastic substrates to fabricate a thermoplastic-based closed microfluidic device and examine the feasibility of using the proposed method for realizing plastic–plastic bonding. The proposed bonding strategy was realized by first coating amine functionality on an oxidized thermoplastic surface. Next, the amine-functionalized surface was reacted with a monolayer of low-molecular-weight PDMS, terminated with epoxy functionality, by forming a robust amine-epoxy bond. Both the PDMS-coated thermoplastic and PDMS were then oxidized and permanently assembled at 25 °C under a pressure of 0.1 MPa for 15 min, resulting in PDMS-like surfaces on all four inner walls of the microchannel. Surface characterizations were conducted, including water contact angle measurement, X-ray photoelectron spectroscopy (XPS), and fluorescence measurement, to confirm the successful coating of the thin PDMS layer on the plastic surface, and the bond strength was analyzed by conducting a peel test, burst test, and leakage test. Using the proposed method, we could successfully bond various thermoplastics such as poly(methylmethacrylate) (PMMA), polycarbonate (PC), polystyrene (PS), and poly(ethylene terephthalate) (PET) with PDMS without the collapse or deformation of the microchannel, and the proposed method was successfully extended to the bonding of two thermoplastics, PMMA, and PC.
