一种抗热氧老化PPS/大内腔HNTs杂化纤维及其制备方法
摘要：
本发明提供了一种抗热氧老化PPS/大内腔HNTs杂化纤维，其特征在于，包括聚苯硫醚PPS切片98-99.9wt％和大内腔HNTs 0.1-2wt％。本发明的PPS/大内腔HNTs杂化纤维具有较强的断裂强度；在180℃热氧老化处理24h后，仍具有较高的力学性能保持率，为61.4-73.4％；其中的HNTs具有大内腔结构，其内径比常见HNTs大3-25nm，具有良好的传热性能。
摘要（英）：

The invention provides a thermo-oxidative ageing resistant PPS (polyphenyl thioether)/ large-inner-cavity HNTs (halloysite nanotubes) hybrid fiber. The thermo-oxidative ageing resistant PPS/ large-inner-cavity HNTs hybrid fiber is characterized by comprising 98-99.9wt% of polyphenyl thioether (PPS) slices and 0.1-2wt% of large-inner-cavity HNTs. The thermo-oxidative ageing resistant PPS / large-inner-cavity HNTs hybrid fiber has strong breaking strength; after being under thermo-oxidative ageing treatment at 180 DEG C for 24h, the thermo-oxidative ageing resistant PPS/large-inner-cavity HNTs hybrid fiber still has high mechanical performance conservation rate being 61.4-73.4%; and the HNTs adopt a large-inner-cavity structure, and the inner diameter of the HNTs is greater than that of common HNTs by 3-25nm, and the thermo-oxidative ageing resistant PPS/large-inner-cavity HNTs hybrid fiber has good heat transfer performance.
