A biocompatible coating consists of a poly(vinyl acetate)/hydroxyapatite (PVAc/HA) composite nanofiber mat was applied to NaOH-treated titanium metal by means of a novel, facile and efficient air jet spinning (AJS) approach. Results showed that HA nanoparticles (NPs) strongly embedded onto the AJS single fiber surface resulting in a strong chemical interfacial bonding between the two phases due to the difference in kinetic energies. It was proven that AJS membrane coatings can provide significant improvement in the corrosion resistance of titanium substrate. Interestingly, the biocompatibility using MC3T3-E1 osteoblast to the PVAc/HA fiber composite layer coated on Ti was significantly higher than pure titanium-substrates.
一种生物相容性涂层由聚醋酸乙烯酯/羟基磷灰石（PVAc/HA）复合纳米纤维毡组成，通过新颖、简便、高效的空气射流纺丝（AJS）方法应用于经 NaOH 处理的钛金属。结果表明，由于动能的差异，HA 纳米颗粒（NPs）强烈嵌入 AJS 单纤维表面，导致两相之间具有强的化学界面结合。证明 AJS 膜涂层可以显著提高钛基体的耐腐蚀性。有趣的是，使用 MC3T3-E1 成骨细胞对涂覆在 Ti 上的 PVAc/HA 纤维复合材料层的生物相容性明显高于纯钛基底。
