【摘要】 使用HI-13串列加速器产生的32S离子对不同厚度的聚酯膜进行不同密度的辐照,并在不同温度、不同碱度和不同蚀刻时间条件下,针对蚀刻对孔形状、孔径以及膜表面损耗的影响等进行了研究。在蚀刻后的样品表面镀金属膜,对镀膜后样品的抗金属污染的绝缘性能进行了研究。结果显示,核孔的存在使材料抗金属污染的绝缘性能得到了大幅提高。更多还原

【Abstract】 Polyester membranes with different thickness were bombarded by 32S ions from the HI-13 tandem accelerator of China Institute of Atomic Energy.The bombarded membranes with different densities of tracks were etched at different conditions,such as etching time,concentration of sodium hydroxide solution and temperature.The effects of etching condition on the pore shape and pore size were also investigated.The insu-lating capability of anti-metallic contamination of treated membranes was evaluated by using silver coatings.The results indicate that the insulating capability of nuclear pore-modified materials in anti-metallic contamination is greatly improved.更多还原
