“…She et al observed that wetting AAO membranes having a D p -value of 200 nm with polyamide 66 at 250 • C yielded nanowires [68]. Similar results were obtained for poly(propylene) [69]. Correspondingly, at a given infiltration temperature and for a given polymer, precursor wetting will occur if the molecular weight of the polymer is relatively low, whereas capillary wetting will occur in the case of relatively high molecular weights.…”

“…When the diameter of the pores in the hard template is reduced below about twice the radius of gyration of the infiltrated polymeric species, the hollow space in the tubes disappears and solid rods are obtained [64][65][66][67]. In general, precursor wetting takes place if the pore walls of the hard template exhibit high surface energy and if the polymeric melts are heated to temperatures well above their glass transition temperature [61,68,69]. However, many aspects of precursor wetting still need to be elucidated.…”

“…The infiltration of solutions consisting of a polymer and a volatile low molecular mass solvent into nanoporous hard templates has been intensively investigated [13,65,68,69,[77][78][79][80][81]. In principle, it is sufficient to drop the solution onto the hard template and to let the solvent evaporate.…”

ABSTRACT:Polyamide 66 (PA66) nanotubes were prepared by filtrating a PA66 solution into pores of anodic aluminum oxide (AAO) template. The AAO/PA66 nanotubes composite membrane can be used as a secondary template. Pt nanowires were then fabricated in the polymer nanotubes of the secondary template by electrochemical deposition method. Nanocables from Polyamide 66 nanotubes embedded Pt nanowires were successfully obtained. Scanning electron microscopy (SEM) and Transmission electron microscope (TEM) were employed to characterize the structure and morphology of one-dimension nanomaterials. We find that the polymer nanotubes enveloping Pt nanowires have a higher thermal-decomposition temperature than the bulk counterpart. The unique property will be beneficial to their application under a higher temperature. [doi:10.1295/polymj.PJ2007008] KEY WORDS Nanocables / Nanotubes / AAO / Secondary-template Method / One-dimensional (1D) nanostructure has been a subject of intensive research interest because of its unique properties and potential applications.1 In particular, nanowires, 2,3 nanotubes, 4-6 and nanocables 7,8 have attracted considerable attention. Martin and his co-workers 9-12 were the first who used AAO membrane-based-on-template method to prepare 1D nanomaterials. Subsequent studies have reported that various nanomaterials such as nanotubes and nanowires composed of metals, semiconductors, polymers, and their composites can be fabricated using the template synthesis method.13 These 1D nanostructures can be used as nanodevices for nanotechnology. 14 However, metal nanowires are sensitive to many environments such as high temperature, air and humidity. Even the noble metal platinum nanowires react easily owing to their nanostructure, which seriously limits their application in many fields. So a polymer sheath can be used to enclose the metal nanowires to protect them from oxidation and corrosion. Previously, conducting polymers have been used to protect metal nanowires. 13,[15][16][17][18] The polymers are seriously reactive with oxygen due to the conjugated structure. Although some non-conducting polymers have been reported using to protect the metal nanowires, the results are not perfect because of the intricate preparing process and the prepolymer they used. For example, Poly (p-xylylene) nanotubes were used to protect the Pd nanowires. 19-21Recently, we have prepared several polymer nanotubes into AAO template nanopores via a simple solution wetting technique. [22][23][24] The obtained PA66 nanotubes enveloped into AAO can be used as a ''secondary template'', into which the metal nanowires are prepared by electrochemical deposition. The polymer/metal nanocables are formed at last. This technique for preparing nanocables can be defined as secondary template method. Many nanocables have been fabricated in our lab in this way. Herein, taking PA66/ Pt nanocables for example, the secondary template method was clearly demonstrated. It is believed that the method described here can be widely used in preparing oth...
