Abstract:

One dimensional nanostructures are well posed to stay at the forefront of materials research for a long time. Their promise as high performance functional elements in electronics, photonics and other sensing/actuation applications is supported by a myriad of synthesis, ordering and manipulation techniques. One such perspective could be the fabrication of nanowires that truly bridge the nano and macro worlds addressing high-throughput, accessibility and simplicity. Here, we report a simple top-to-bottom production method to obtain kilometer long, ordered, semiconducting and polymer nanowires and nanotubes with uniform diameter, homogenous distribution, and endlessly parallel orientation. A novel iterative thermal size reduction technique is used to stepwise reduce a macroscopic rod down to ordered arrays of extremely long nanowires a polymer matrix. In this way, we produced for the first time, millions of ordered, indefinitely long, polymer embedded nanowires, nanotubes and core-shell arrays. Obtained wire diameter’s range are as wide as 10 nm to 100 micrometer, and are highly uniform.
