Abstract:

Several basic physical properties of poly(arylene ether ketone)s containing N-alkylcarbazole(PPCzE, PPCzB and PPCzH) were studied in comparison with the corresponding analog, commercialized phenolphthalein poly(ether ketone)(PEK-C). Strong UV absorption and blue light emission ability are exhibited by these polymers due to the introduction of carbazole structure. The water contact angle of polymers(87°~103°) is greater than that of PEK-C(76°), because of the hydrophobic nature of alkyl groups. While at the same time, these polymers have higher water uptake capabilities than PEK-C which is probably due to their larger chain distance. In addition, these polymers exhibit good dimensional stability(linear thermal expansion coefficient 6.4×10-5-1) and electrical insulating(volume resistivity 1016 Ω·cm) property. Young's modulus, tensile strength and elongation at break of these polymers are in the range of 1.9~2.0 GPa, 72.5~75.0 MP and 6.5%~7.2%, respectively. Dynamic mechanical analysis shows that PPCzE remains good tensile property at the temperature up to 225 ℃.
