This study fabricated polymer–metal hybrid (PMH) materials with ultrahigh strengths using an effective electrochemical treatment strategy and direct molding bonding. It is found that the bonding strength of the prepared PMH between the polymer and metal reached as high as 21.0 MPa. Characterizations revealed the formation of a new multinanoporous Al2O3 layer on an aluminum (Al) alloy after electrochemical treatment. The thickness of the Al2O3 layer was 6.2–15.3 μm, and nanopores with an average diameter of 7.8–14.3 nm were parallelly distributed throughout the whole Al2O3 layer. The formation of countless nanorivets allows large-area mechanical interlocking at the interface between the polymer and Al alloy, which is thought to be the key mechanism of achieving ultrahigh strength. At the optimal treatment voltage of 18 V, the maximum mechanical strength of the PMH material was obtained, and the corresponding number of the formed nanorivets was 5.75 × 1010 in theory. Also, the average size of the nanopores was 14.3 nm. Compared to the traditional chemical treatments, the electrochemical method is no doubt a more effective treatment.

基于电化学产生的纳米孔的机械互锁，具有超高界面强度的聚合物-金属杂化材料
这项研究使用有效的电化学处理策略和直接成型粘合工艺制造了具有超高强度的聚合物-金属杂化（PMH）材料。发现所制备的PMH在聚合物和金属之间的结合强度高达21.0MPa。表征表明，经过电化学处理后，铝（Al）合金上形成了新的多纳米孔Al 2 O 3层。Al 2 O 3层的厚度为6.2-15.3μm，平均孔径为7.8-14.3 nm的纳米孔在整个Al 2 O 3中平行分布层。无数纳米铆钉的形成允许在聚合物和铝合金之间的界面处进行大面积的机械互锁，这被认为是实现超高强度的关键机制。在18 V的最佳处理电压下，获得了PMH材料的最大机械强度，并且理论上相应形成的纳米铆钉数为5.75×10 10。另外，纳米孔的平均尺寸为14.3nm。与传统的化学处理相比，电化学方法无疑是一种更有效的处理方法。
