“…Below this concentration, the PEI does not influence the PEEK crystallinity [20]. A decrease in the crystallization with increasing PEI content was measured [20,21,26,61,62,100,104,111,112], attributed to a rejection of PEI into the amorphous domains of PEEK [20]. The final degree of crystallinity of the PEEK reached in the blends did not change with the PEI content and in some cases slightly increased [20,21,26,62,101,111].…”

“…They give fully miscible blends at all compositions in the amorphous state. Indeed, all reports reviewed measured a single T g on quenched samples, either using DSC or DMTA [19,20,25,[27][28][29][30]61,62,[100][101][102][103][104], over the whole range of composition. Good agreement between the values of the measured T g and Fox equation is found in those works, as illustrated in Figure 15.…”

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.

Investigation of morphologies and tensile impact toughness of immiscible polyphenylene sulfide/polyether sulfone films and carbon fiber composites by quantitative optical methods

Targeting the transfer and improvement of impact toughness in composites deriving from polymer mixtures, we investigated the effectiveness of immiscible polyphenylene sulfide (PPS)/polyether sulfone (PES) blends reinforced by endless carbon fibers. Tensile impact testing of films and composites was performed. Impact strengths of films showed high dependency of the PPS crystallinity and crystal orientation influenced by the present amount of PES. Intermolecular interactions between the immiscible phases and the presence of amorphous areas were assumed to be the driving factor for the load transfer in these films. Optical evaluation of local and global strain at break of films revealed a significant increase in plasticization. Tensile impact tested ±45 carbon composites exhibited high improvements of toughness and deformation ability provided by the PES spheres. The quantification of morphologies evidenced a strong correlation of PES profile's mean diameters and next neighbor distances with impact toughness and deformation ability, qualifying these novel materials as potential alternatives for conventional high-end composites.
