Ag和Ni离子注入聚合物的分形生长

FRACTAL GROWTH FOR Ag^+ AND Ni^(2+) IMPLANTED POLYMER

在Ag和Ni离子注入聚合物样品结构分析中 ,首次观察到注入的离子在聚合物中分形生长现象 ,用透射电子显微镜和扫描电子显微镜在注入样品表面与横截面处均观察到了漂亮的离子注入分形生长图 .讨论了分形特点和分形生长的机理 。

The structure of Ag + and Ni 2+ implanted polymer (PET) is analyzed. Fractal growth in Ag and Ni implanted polymer is found for the first time. Beautiful fractal patterns are observed using transmission and scanning electron microscope. The properties and mechanism of fractal growth are discussed. The results are compared with CLDA model calculation.
