摘要

聚偏氟乙烯(PVDF)是一种具有优异柔韧性、机械强度和生物相容性的压电聚合物。α-相PVDF具有优异的摩擦学性能,而β-相PVDF具有优异的压电性能。为了实现这两种性能的协同优化,必须对PVDF进行有效的改性。本研究采用静电纺丝法制备PVDF纳米纤维膜,碳纳米管(CNT)作为结构调节剂,平衡α-相和β-相的含量。结果表明,与纯PVDF相比,摩擦系数(COF)降低了14.4%,负表面电位得到了缓解,使其分布更加均匀和稳定。双增强显著提高了摩擦性能和压电性能。碳纳米管导致摩擦声信号的稳定性增加,反映了复合系统的润滑协同效应。CNTs的存在极大地改善了膜的润湿性,实现了稳定的模拟体液(SBF)接触角仅为29.07°。改性后的PVDF/CNT膜也表现出增强的Ca2+吸附能力,即使在摩擦磨损后仍保持良好的保留,有利于形成稳定的生物润滑层。PVDF/CNT纳米纤维膜在润滑、耐久性和生物相容性方面的综合增强突出了PVDF/CNT纳米纤维膜作为下一代人工关节植入物先进生物材料涂层的巨大潜力。

Electrospun PVDF/CNT nanofiber membranes with synergistic optimization of tribological and piezoelectric properties for artificial joint implant coatings
Polyvinylidene fluoride (PVDF) is a piezoelectric polymer with outstanding flexibility, mechanical strength, and biocompatibility. α-phase PVDF exhibits excellent tribological properties, while β-phase PVDF is known for its superior piezoelectric performance. To achieve a synergistic optimization of both properties, PVDF must be effectively modified. In this study, electrospinning was employed to fabricate PVDF nanofiber membranes, with carbon nanotubes (CNT) incorporation serving as a structural regulator to balance the α-phase and β-phase content. As a result, the coefficient of friction (COF) was reduced by 14.4 % compared to pure PVDF, and the negative surface potential was mitigated, leading to a more uniform and stable distribution. The dual enhancement significantly improved both tribological and piezoelectric performance. CNT leads to an increase in the stability of the friction acoustic signal, reflecting the lubrication synergy effect of the composite system. The presence of CNTs greatly improved the wettability of the membrane, achieving a stable simulated body fluid (SBF) contact angle of just 29.07°. The modified PVDF/CNT membrane also demonstrated enhanced Ca2+ adsorption capability, maintaining excellent retention even after frictional wear, facilitating the formation of a stable bio-lubrication layer. The combined enhancements in lubrication, durability, and biocompatibility highlight the great potential of PVDF/CNT nanofiber membranes as advanced biomaterial coatings for next-generation artificial joint implants.
