| Research Abstract |
The author developed carbon powders for electromagnetic wave shielding and absorption material, which was made from three kinds of agricultural by-products, i.e. rice hull, soy hull, and plant skin. The plastic composite materials with the carbon powders were manufactured by mixing the powder and polyethylene fiber, using a wet-papermaking method. The electric conductivity, the electromagnetic wave shielding and absorption properties were measured for the composite materials. Especially, the effect of powder species, the powder content and the thickness of the composite materials were discussed. Finally, the design method were discussed to obtain a optimum electromagnetic wave absorption material, using the transmission line theory.
