【Abstract】 Highly ordered nanoporous nickel me mbranes were fabricated by a two-ste p replication of porous anodic alumina with honeycomb structure.SEM analysis shows that the nan oholes of nickel membranes are hexagonally arranged in high regula rity.The mean diameter and the interval of the holes measured from the SEM micrograph are about 40nm and 80nm,r espectively.The mean diameter of th e hole array was dependent on the corresponding parameter of the poro us anodic alumina.Compared with alu mina membranes,the nanoporous meta l ones have many advantages in more suf ficient thermal,chemical stability and higher mechanical strength.Serving as a magnetic and conductive materia l,the nickel membrane template will be used for many technological and sc i-entific applications.The presente d process could be utilized to fabric ate nanostrctures of other nanochan nel materi-als.更多还原
