In situ synthesis of composite nanowires consisting of metal nanoparticles in ion-exchangeable polymer matrix using porous alumina templates

  One-dimensional (1D) superstructures constructing of inorganic nanoparticles have unique and technologically important potential applications in the areas of nanoelectronics, plasmonics, and molecular sensors. Herein, we describe how nanoporous template and in situ synthetic process can be combined for the construction of composite nanowires consisting of silver nanoparticles dispersed in polymer matrices. We show that, by limiting the space where nanoparticles grow, the silver nanoparticles are encapsulated inward within the polymer nanowires. We also demonstrated that the composite microstructure could be controlled by varying the initial precursor structure, pore size of the template and temperature.
