在公开文献中发表的关于各种聚合物金属杂化（PMH）方法用于促进金属和注塑成型热塑性塑料之间的直接（无粘合剂）粘合的工作进行了回顾和批评。不同的方法分类如下：(a)微尺度聚合物-金属机械联锁；(b)线圈内或冲压件预涂膜，以增强附着力；(c)对注塑成型的热塑性塑料进行化学改性，以增强聚合物与金属的附着力。对于这些方法中的每一种，都讨论了它们在承重白车身（BIM）组件中使用的适用性。特别是，这些方法与白车身制造工艺链的兼容性（即预涂覆金属部件冲压，通过不同连接技术的白车身结构，白车身预处理和涂装操作）。人们发现，虽然在PMH直接粘附领域已经进行了大量的研究，但这些技术的许多方面都没有得到解决（或正确解决），这些技术从其在白车身结构应用中的使用角度来看是至关重要的。在已确定的PMH技术中，基于注塑成型热塑性聚合物和冲压金属结构肋构件之间的微尺度机械互锁的PMH技术似乎是最有前途的。(c) 2007 Elsevier B.V.版权所有
The work published in the open literature dealing with various polymer metal hybrid (PMH) approaches used to promote direct (adhesive-free) adhesion between metal and injection -molded thermoplastics is reviewed and critiqued. Different approaches are categorized as follows: (a) micro-scale polymer-to-metal mechanical interlocking; (b) in-coil or stamped-part pre-coating for enhanced adhesion; and (c) chemical modifications of the injection-molded thermoplastics for enhanced polymer-to-metal adhesion. For each of these approaches their suitability for use in load-bearing body-in-white (BIM components is discussed. In particular, the compatibility of these approaches with the BIW manufacturing process chain (i.e. pre-coated metal component stamping, BIW construction via different joining technologies, BIW pre-treated and painting operations) is presented. It has been found that while considerable amount of research has been done in the PMH direct-adhesion area, many aspects of these technologies which are critical from the standpoint of their use in the BIW structural applications have not been addressed (or addressed properly). Among the PMH technologies identified, the one based on micro-scale mechanical inter locking between the injection -molded thermoplastic polymer and stamped-metal structural rib component appears to be most promising.
