fabrication of polymer-sio2 nanocomposite optical fibers with a new method

At first step polymer optical fibers (pofs) are used in short distance for optical data transmissions. at second step sio2 nanoparticles were prepared by sonochemical-assisted method. finally silica nanoparticles were added to polymer matrix to prepare polymer based nanocomposites. most of the pof applications are in the medical and electrical devices. there are several methods for fabrication of pofs, description of which are given in this paper. we have designed a special co-extruder system for fabricating pof. the pofs fabricated by this device are very homogeny and their core and cladding have good viscidity.
