| 摘 要： | 为提高氧化铝磨料分散稳定性,利用接枝聚合对氧化铝粒子进行了表面改性,并研究了改性后氧化铝粒子在数字光盘玻璃基片中的化学机械抛光特性。结果表明,氧化铝复合磨粒的抛光性能与其表面接枝率密切相关。接枝率上升,材料去除速率下降;试验条件下,当接枝率为2.93%时,氧化铝磨粒体现出较高的表面平整性、较低的表面粗糙度及较低的表面损伤。

| Abstract: | In order to enhance the dispersion stability of alumina abrasive and prevent agglomeration in chemical mechanical polishing(CMP),the surface modification of alumina particles with grafting polymerization was conducted.SEM indicates that alumina particles with grafting modification have better dispersion stability than that unmodified.The polishing performances of the prepared alumina composite abrasive on digital compact disc(CD) glass substrate were investigated.The results that the polishing performances of the alumina composite abrasive are much dependent on the grafting ratio.With the increasing of grafting ratio,the material removal rate decreases gradually.By comparison with pure alumina abrasive,the alumina composite abrasive with 2.93% grafting ratio exhibites higher surface planarization,lower surface roughness and less surface scratches. |
