本文阐述了一种经济高效的策略，通过受贻贝启发的表面改性和化学镀铜 (ECP) 在聚苯硫醚 (PPS) 上制造高性能金属铜层，用于高频微波应用。通过紫外线诱导的儿茶酚（CA）/聚胺（PA）表面修饰，修饰后的PPS基材能够吸附银颗粒，为后续的ECP提供激活位点。 CA/PA 改性对 PPS 和沉积铜层之间关系的影响可以通过水接触角测量、X 射线光电子能谱 (XPS)、X 射线衍射 (XRD) 和胶带剥离测试来确定。 CA/PA的介入成功地在PPS表面引入了化学键合的官能团，大大提高了PPS与沉积铜层之间的附着力。此外，经过 40 分钟的 ECP 后，所生产的铜层表现出良好的 5B 级附着力（根据 ASTM D3559）和 0.37 S/m 的优异电导率（约为块状铜的 62%）。同时，沉积铜层还具有良好的耐酸、碱、盐腐蚀能力（腐蚀60 h后单位面积失重小于25 g/m2）。这种方法为PPS的表面金属化开辟了一条有效的途径，PPS在高频覆铜板（CCL）中具有广泛的应用潜力。
An economical and efficient strategy for fabricating high-performance metallic copper layers on polyphenylene sulfide (PPS) for high-frequency microwave applications via mussel-inspired surface modification and electroless copper plating (ECP) is illustrated in this paper. Through UV-induced surface modification of catechol (CA)/polyamine (PA), the modified PPS substrate is capable of adsorbing silver particles, which provides activation sites for subsequent ECP. The impact of CA/PA modification on the relationship between PPS and the deposited copper layer can be determined by water contact angle measurements, X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and tape peel tests. The involvement of CA/PA has successfully introduced the functional groups for chemical bonding on the PPS surface, which greatly improves the adhesion between the PPS and the deposited copper layer. Moreover, after 40 min of ECP, the produced copper layer exhibits good adhesion at the 5B level (according to the ASTM D3559) and an excellent conductivity of 0.37 S/m (approx. 62% of bulk copper). Meanwhile, the deposited copper layer also has good resistance to acid, alkali, and salt corrosion (less than 25 g/m2 per unit area weight loss after 60 h of corrosion). This approach opens up an efficient path for the surface metallization of PPS, which has a broad potential for application in high-frequency copper-clad laminates (CCLs).
