A series of blends with various compositions are prepared by melt extrusion on the basis of novel copoly(phthalazinone biphenyl ether sulfone) (PPBES) and poly(ether ether ketone) (PEEK).

Influence of the addition of lubricant on the properties of poly(ether ether ketone) fibers

A high‐temperature lubricant genioplast pellets (GPPS) was used in order to improve the processing behavior of poly(ether ether ketone) (PEEK) resin and high‐performance PEEK fibers were produced by melt‐spinning. The rheological properties of spinning material, morphology, mechanical, and thermal properties of PEEK fibers were characterized by using a polymer capillary rheometer, scanning electron microscopy, single fiber electronic tensile strength tester, wide‐angle X‐ray diffraction and thermal gravimetric analyzer, respectively. The results indicated that the introduction of lubricant GPPS decreased the melting viscosity of PEEK resin and improved spinnability of PEEK resin without sacrificing its thermal properties. The filaments are cylindrical with smooth surface and uniform diameter. The optimized content of GPPS was determined to be 1.0 wt% by balancing the decreased torque and changes of the mechanical properties. The strength and modulus of PEEK fibers were 420 MPa and 3.6 GPa, respectively. This should be due to the improvement in spinnability, followed by the enhancements in the orientation and crystallization of PEEK fibers in the process of drawing and annealing. POLYM. ENG.

The improved interface performance between carbon fiber and poly(ether-ether-ketone) by sulfonated polyether sulfone (s-PSF) sizing agent with different sulfonation degree

The effects of sulfonated polyether sulfone (s-PSF) with different sulfonation degrees on the interfacial properties of carbon fiber (CF)/poly(ether-ether-ketone) (PEEK) composites were investigated systematically. The performance of the modified CF and the corresponding CF/PEEK composites and was tested and characterized. Test results show that the CF surface polarity increases, the surface contact angle decreases, and the surface free energy increases with the increase in the s-PSF sulfonation degree. Scanning electron microscopy analysis shows that the increase in the sulfonation degree of s-PSF is beneficial to improve the interface between CF and PEEK. This condition can be ascribed to the hydrogen bonding force between the s-PSF sulfonic acid group and the polar functional group on the surface of the modified CF and the compatibility between s-PSF and PEEK. In terms of physical properties, the thermal and mechanical properties of CF/PEEK composite are improved with the increase in s-PSF sulfonation degree. The interlaminar shear strength, flexural strength, and modulus of CF/PEEK composites increase by 60.16%, 30.27%, and 19.30%, respectively.     

Isothermal crystallization kinetics of PEEK/Vectra® blends by DSC and time‐resolved synchrotron X‐ray diffraction

Thermal properties of blends of poly(aryl ether ether ketone), PEEK, with a thermotropic liquid crystalline polymer, Vectra®, were investigated by differential scanning calorimetry and X‐ray diffraction techniques. Isothermal crystallization experiments were performed over a wide range of crystallization temperatures and compositions to follow the effect of Vectra® content on the crystallization kinetics of PEEK. A reduction in the crystallization rate of PEEK was related to a change in the mechanism of crystallization of PEEK, controlled in turn by the concentration of Vectra® in the blend. The addition of Vectra® resulted in a significant enhancement in the crystallization rate of PEEK. In addition, a reduction in this parameter is shown at a blend of 30% of Vectra®. Differences in the crystallization behavior of PEEK are related to structural properties of these systems measured by simultaneous real time WAXS and SAXS experiments using synchrotron radiation. Results of melting behavior of PEEK, subsequent to isothermal crystallization, were interpreted based on the effects of Vectra® on the formation of two crystal families of PEEK. Melting temperatures of PEEK and crystallinity calculated from double endotherm are influenced by blending. POLYM. ENG. SCI., 46:1411–1418, 2006. © 2006 Society of Plastics Engineers
