Abstract

Polyether ether ketone (PEEK) has been extensively used in healthcare due to its excellent mechanical properties, chemical resistance, and biocompatibility. Still, its weak bactericidal performance allows pathogenic bacteria to easily adhere to and proliferate on the PEEK surface. In this research, physical plasma treatment and chemical fluoridation have been combined to enable the PEEK surface with stable antibacterial performance. The characteristics of surface morphology, elemental composition, and hydrophilicity for the samples have been characterized. In vitro experiments reveal that the obtained PEEK surface exhibited great antimicrobial activity. Furthermore, the antimicrobial effect of the modified PEEK surface has shown almost no variation after 28 days of storage at room temperature and 4 h at 121 °C, confirming its excellent storage property and high-temperature stability. This study presents an efficient and practical method to enhance the cytocompatibility and the antimicrobial properties of the PEEK surface, making it a potential medical device material.

等离子体辅助氟化聚醚醚酮以获得稳定的抗菌性能

聚醚醚酮（PEEK）具有优异的机械性能、耐化学性和生物相容性，已被广泛应用于医疗保健领域。然而，由于其杀菌性能较弱，致病细菌很容易附着在 PEEK 表面并在其上繁殖。在这项研究中，物理等离子处理和化学氟化相结合，使 PEEK 表面具有稳定的抗菌性能。实验表明，获得的 PEEK 表面具有很强的抗菌活性。此外，改性后的聚醚醚酮表面在室温下存放 28 天和 121 ℃ 下存放 4 小时后，其抗菌效果几乎没有变化，这证实了其优异的储存性能和高温稳定性。本研究提出了一种高效实用的方法来增强聚醚醚酮表面的细胞相容性和抗菌性，使其成为一种潜在的医疗器械材料。
