This review aims to report the status of the research on polyaryletherketone-based thermoplastic blends (PAEK). PAEK are high-performance copolymers able to replace metals in many applications including those related to the environmental and energy transition. PAEK lead to the extension of high-performance multifunctional materials to target embedded electronics, robotics, aerospace, medical devices and prostheses. Blending PAEK with other thermostable thermoplastic polymers is a viable option to obtain materials with new affordable properties. First, this study investigates the miscibility of each couple. Due to different types of interactions, PAEK-based thermoplastic blends go from fully miscible (with some polyetherimides) to immiscible (with polytetrafluoroethylene). Depending on the ether-to-ketone ratio of PAEK as well as the nature of the second component, a large range of crystalline structures and blend morphologies are reported. The PAEK-based thermoplastic blends are elaborated by melt-mixing or solution blending. Then, the effect of the composition and blending preparation on the mechanical properties are investigated. PAEK-based thermoplastic blends give rise to the possibility of tuning their properties to design novel materials. However, we demonstrate hereby that significant research effort is needed to overcome the lack of knowledge on the structure/morphology/property relationships for those types of high-performance thermoplastic blends.
本综述旨在报告基于聚芳醚酮的热塑性共混物（PAEK）的研究现状。PAEK是一种高性能共聚物，在包括与环境和能源转型相关的许多应用中能够替代金属。PAEK使得高性能多功能材料得以扩展，以应用于嵌入式电子、机器人技术、航空航天、医疗设备和假体。将PAEK与其他热稳定热塑性聚合物共混是获得具有新的经济适用性能材料的可行选择。首先，本研究考察了每一对共混物的相容性。由于相互作用类型不同，基于PAEK的热塑性共混物从完全相容（与一些聚醚酰亚胺）到不相容（与聚四氟乙烯）。根据PAEK的醚酮比以及第二组分的性质，报道了大范围的晶体结构和共混形态。基于PAEK的热塑性共混物通过熔融共混或溶液共混制备。然后，研究了组成和共混制备对力学性能的影响。基于PAEK的热塑性共混物使得调整其性能以设计新型材料成为可能。然而，我们在此证明，需要付出巨大的研究努力来克服对于这类高性能热塑性共混物在结构/形态/性能关系方面缺乏了解的问题。
