Py rrole to polypyrrole/Ag nano composites via emu lsion pol ymerization

In recent years, the interest in the development of inorganic/organic com posite has g rown rapidly due to a wide range of potential use of these materials [۱]. Among th ese materials, one important class is that in which the organic part is con ducting polymers, such as polyaniline or polyp yrrole [۲]. Polypyrrole as one of the most prom ising cond ucting poly mers has received comprehensive i nterests due to its excellent characteristics including e asy preparation,environmental stability, high conductivity and so on. The mention ed merits lead polypyrrole to have wide potential applications in various fields, such as sensors, actua tors and electric device s. On the other hand, the metal nanoparticl es, such as silver, have attracted much attention in rece nt years due to their interesting properties and potential applications in techno logical fiel ds. Silver particles have applications in catalysis, conductive inks, thic k film pastes and adhesi ves for vario us electronic componen ts, in photonics and in photography [۳]. So fa r, various m ethods for Polypyrrol e/silver (PPy/Ag) nano composites preparation have been r eported. Ho wever, the preparation of them by emulsion method start ing from p yrrole and silver has not been reported yet. Our target of thi s study is to introduce a new meth od for the pr eparation of this class of electro-active materials .
