羟基磷灰石是一种磷酸钙生物陶瓷材料,具有优异的生物相容性和生物活性,但强度低、韧性差的特点限制了其广泛应用。碳纳米管具有优异的力学性能和良好的生物相容性,是一种良好的增强补韧材料。碳纳米管增强羟基磷灰石生物陶瓷材料是目前国内外研究的热点,具有重要的理论及实际应用意义。本文简述了碳纳米管增强羟基磷灰石复合材料的研究现状,对其制备方法及性能进行了简要总结分析。
Hydroxyapatite is a calcium phosphate bioceramic material with excellent biocompatibility and biological activity, but its low strength and poor toughness limit its wide application. Carbon nanotubes with excellent mechanical properties and good biocompatibility, is a good reinforcement toughening materials. Carbon nanotubes reinforced hydroxyapatite bioceramic materials are the hotspots at home and abroad, and have important theoretical and practical significance. In this paper, the current research status of carbon nanotubes reinforced hydroxyapatite composites is briefly reviewed, and their preparation methods and properties are summarized briefly.
