Abstract

The principal possibility of synthesis of composite particles by the radiation-chemical method was shown. The composite particles were produced on the nanoscale range (50–80 nm) from aluminum oxide partially coated with silver. The coating percentage varied from 2–3 % to 16–40 %. The results of stabilization using polyethylene glycol and sodium citrate showed low sedimentation stability of the suspension. In addition, the biological activity of the nanopowder was investigated that showed a high level of antibacterial activity.The principal possibility of synthesis of composite particles by the radiation-chemical method was shown. The composite particles were produced on the nanoscale range (50–80 nm) from aluminum oxide partially coated with silver. The coating percentage varied from 2–3 % to 16–40 %. The results of stabilization using polyethylene glycol and sodium citrate showed low sedimentation stability of the suspension. In addition, the biological activity of the nanopowder was investigated that showed a high level of antibacterial activity.

Al2O3+Ag复合纳米粉体的合成与表征

指出了用辐射化学方法合成复合粒子的主要可能性。在50 ~ 80 nm的纳米尺度上，用部分镀银的氧化铝制备了复合颗粒。涂布率从2 - 3%到16 - 40%不等。聚乙二醇和柠檬酸钠的稳定结果表明，该悬浮液的沉降稳定性较低。此外，对纳米粉末的生物活性进行了研究，发现其具有较高的抗菌活性。指出了用辐射化学方法合成复合粒子的主要可能性。在50 ~ 80 nm的纳米尺度上，用部分镀银的氧化铝制备了复合颗粒。涂布率从2 - 3%到16 - 40%不等。聚乙二醇和柠檬酸钠的稳定结果表明，该悬浮液的沉降稳定性较低。此外，对纳米粉末的生物活性进行了研究，发现其具有较高的抗菌活性。
