采用物理共混法(PB)、化学共沉积法(CC)和仿生浸泡法(BI)合成了多壁碳纳米管/羟基磷灰石复合粉(MWNTs/HA),并将其作为磷酸钙骨水泥(CPC)的固相粉末之一,分别制备了相应的CPC样品.由于MWNTs对液相中水分子的吸附、毛细管作用以及表面存在较多的亲水基团,使得含有MWNTs的CPC样品的亲水性得以提高,且初凝时间和终凝时间都有所缩短,但仍满足临床应用的要求.由于CPC中的MWNTs/HA复合粉末的合成方式不同,使之对CPC的抗压性能、CPC中HA的结晶性、微观形貌影响均较大,但并不影响CPC的晶相组成.其中PB法所合成的MWNTs/HA复合粉末能促进CPC中纳米级HA晶体的转化和生长,使针状HA含量的表现为最高,且抗压力学性能为最好,其抗压强度和弹性模量分别较空白CPC提高了48.23％和41.87％.
