摘要
羟磷灰石有与生物骨相似的化学组成和晶体结构,作为骨种植材料备受关注。但它脆性大,力学性能欠佳,临床应用受到局限。近年来,碳纳米管因为具有高强度、高弹性模量、耐扭折等理想的机械性能,被用于羟磷灰石的加强。笔者拟对目前碳纳米管-羟磷灰石复合材料的合成方法和研究现状作一综述。
Hydroxyaptite(HA) has received increasing attention as a bone implant material owing to its similar chemical composition and crystal structure as apatite in the human skeletal system. However, their brittleness and poor strength restrict its clinical applications. Carbon nanotubes have been selected to reinforce the HA considering their ideal mechanical properties, including extreme flexibility and strength, significant resistance to bending ect. This paper tries to review the development of several synthes...
