Conductive fibers from Polypropylene(PP)/Ag particle/CNT are prepared by melt spinning process for high electro conductivity. Fiber is re-highlighted form of complex materials because it shows high flexibility and easy transform benefits. It has high conductivity helping from conductive materials such as metals and carbon materials. Melt spinning is the most difficult process to control the accurate mixing ratio, regulation, and well dispersion, therefore, it is hardly used to fabricate high conductive fibers. However, it is the essential to produce bulk scale because it facilitates fast and cost effective process. In our research, the method to develop the high electro-conductive fiber is attempted through the melt spinning process. Ag powders and one-dimensional carbon materials are prepared to develop the conductive fiber. PP is selected to matrix material because of its low process temperature and easy melt spinning process. In the PP/Ag composite, Ag acts as conductor to transport electrons in PP matrix. Metal positioning is major factor to have high electrical property because only connected metals can flow the electrons. Disconnected metals are unable to act as the electron path, therefore, it is important to control the metal position in polymer matrix for preventing separations. To prevent disconnection, compact screw of 11mm diameter is used to mix polymer with metal. The other trial is using carbon nanotubes(CNTs) as an electron bridge between metal powders. It is thought that CNT network is easy way to connect un-contacted metal powders. As a result, highly conductive fiber from PP/Ag/CNT is obtained successfully. The electrical conductivity is enhanced according to whether CNT is added or not. It is expected that our attempts are basic researches to produce the highly electrical conductive fiber in mass production.
