| 摘 要： | 采用脉冲电化学沉积法在钛金属表面制备出羟基磷灰石/壳聚糖(HA/CS)复合涂层,实现CS与HA在微观尺寸上的复合与杂化.比较了脉冲电位与恒电位模式下复合涂层的形成,研究了电位高低及壳聚糖浓度对复合涂层性能的影响.结果表明,与恒电位模式比较,脉冲电位下制备的涂层较均匀、结晶性好、CS含量高,并且HA与CS杂化程度高.脉冲...

| Abstract: | A pulsed electrochemical deposition(ED) method was employed to produce hydroxyapatite(HA)/chitosan(CS) composite coatings on Ti substrates.HA dispersed uniformly in the CS network.There was nano-scale hybridization between HA and CS due to in situ co-precipitation.ED was conducted in the cell that had three electrodes:a Ti plate as the working electrode,a platinum plate as the counter electrode and a saturated calomel electrode(SCE) as the reference electrode.Electrolytes were aqueous solution of 5 mmol/L C... |
