聚苯硫醚/槲皮素抗氧化纤维的制备及性能
|
摘要
为提高聚苯硫醚(PPS)纤维的抗氧化性能,采用共混改性的方法,用熔融纺丝机制备了PPS/槲皮素复合纤维。探索了PPS/槲皮素复合纤维的可纺性,并分析了改性后复合纤维表面形貌、取向度、拉伸性能、热稳定性以及抗氧化性能。结果表明,槲皮素在PPS纤维中分散较均匀,没有出现较大的团聚颗粒;槲皮素在复合纤维中起到了增塑剂的作用,使复合纤维的取向度提高;随着槲皮素含量的增加,断裂强度先提高后稍有降低,当槲皮素质量分数为0.20%时,PPS复合纤维的断裂强度达到最高值,为15.84cN/tex,较纯PPS纤维提高了17.51%;复合纤维的氧化诱导温度有明显的提升,且在槲皮素质量分数为0.20%时效果最佳,达到了467.3℃,较纯PPS纤维提升了14.9℃。槲皮素分子结构中酚氢基作为自由基捕捉剂,捕捉PPS纤维氧化产生的自由基,抑制其进一步氧化降解。
In order to improve the thermal oxidation performance of polyphenylene sulfide(PPS) fibers,PPS/quercetin composite fibers were prepared by melt spinning machine with blending modification method. The spinnability of PPS/quercetin composite fibers were investigated. The surface morphology,orientation,tensile properties,thermal stability and oxidation resistance of the modified composite fibers were studied. The results indicate that quercetin is more evenly dispersed in PPS fibers,and no large agglomerated particles appear. Quercetin plays a role of plasticizer in PPS fibers,and improves the orientation of composite fibers. With the increase of quercetin content,the breaking strength of composite fibers first increases and then decreases slightly,the breaking strength of composite fibers with the content of 0.20% reaches the highest value of 15.84 cN/tex,which is increased by 17.51%. The oxidation induction temperature of composite fibers is obviously improved,and the effect is best when the content is0.20%,reaching 467.3℃,which is 14.9 ℃ higher than that of pure PPS fibers. The phenolic hydrogen group in the molecular structure of quercetin is used as a free radical scavenger to capture the free radicals generated by the oxidation of PPS fibers and inhibit the further oxidation degradation.
