Abstract

This study explores the isothermal and non-isothermal crystallization behavior of poly(ether ether ketone) (PEEK) nanocomposites reinforced with hydroxyapatite (HA) and zinc oxide (ZnO), with emphasis on the role of filler morphology and hybridization. Differential scanning calorimetry (DSC) combined with Avrami analysis was employed to investigate crystallization kinetics at multiple temperatures. While conventional nanofillers generally delay crystallization due to hindered chain mobility, the incorporation of 2.5 wt.% flower-like ZnO (fZnO) significantly mitigated this effect, showing crystallization behavior comparable to neat PEEK. In contrast, spherical ZnO (cZnO), HA, and their hybrid systems led to extended crystallization times. Despite variations in crystallization rate, melting temperature (T_m) and equilibrium melting temperature (T_m⁰) remained nearly unchanged, indicating preserved lamellar thickness. The results highlight that nanoparticle morphology strongly influences nucleation dynamics, and fZnO offers a promising strategy to tailor crystallization without compromising crystalline structure. These findings provide key insights for designing high-performance PEEK-based materials for structural and biomedical applications.

羟基磷灰石/氧化锌PEEK纳米复合材料结晶动力学：纳米颗粒形态和杂化的影响

本研究探讨了羟基磷灰石（HA）和氧化锌（ZnO）增强聚醚醚酮（PEEK）纳米复合材料的等温和非等温结晶行为，重点研究了填料形貌和杂化的作用。采用差示扫描量热法（DSC）结合Avrami分析研究了不同温度下的结晶动力学。传统的纳米填料通常由于阻碍链迁移而延迟结晶，而加入2.5% wt.%的花状ZnO （fZnO）显著减轻了这种影响，显示出与纯PEEK相当的结晶行为。相反，球形ZnO （cZnO）、HA及其杂化体系导致结晶时间延长。尽管结晶速率发生了变化，但熔化温度（Tm）和平衡熔化温度（Tm0）几乎没有变化，表明层状厚度保持不变。结果表明，纳米颗粒的形貌对成核动力学有很大的影响，而fZnO提供了一种有前途的策略，可以在不影响晶体结构的情况下定制结晶。这些发现为设计用于结构和生物医学应用的高性能peek基材料提供了关键见解。
