Abstract
Provided is a polymer nanowire which contains nanoparticles so as to have new functionalities. A thin film is formed on a substrate and includes functional nanoparticles and polymers, and further includes a photosensitive pigment as required. The thin film is irradiated with a pulsed laser. This causes a polymer nanowire containing the functional nanoparticles to grow from a surface of the thin film.
Claims11
A thin film/polymer nanowire complex comprising:
- a thin film that includes at least one polymer layer including a polymer and at least one nanoparticle layer including nanoparticles, wherein at least one of the polymer layer and the nanoparticle layer includes a photosensitive pigment selected from the group consisting of coumarin, pyrene, perylene, anthracene, porphyrin, and phthalocyanine;
- and
- a polymer nanowire of the polymer containing a plurality of nanoparticles in a distributed manner along the length thereof, the nanoparticles contained in the polymer nanowire being the same type of the nanoparticles as in the thin film, and the polymer nanowire extended from the thin film;
- wherein the polymer includes at least one type of polymer selected from the group consisting of a methacrylate polymer, a polyvinyl polymer, a polythiophene polymer, a polyacetylene polymer, a polyaniline polymer, and a polypyrrole polymer;
- and
- wherein the nanoparticles are a functional material selected from the group consisting of magnetic material, material with optical properties, material with electrical properties, and radiative material.
