Impact of carbonization temperature on activated carbon web for EMI shielding and ohmic heating

Popis výsledku v původním jazyce

In this work porous and electrically conductive activated carbon webs were produced by using acrylic fibrous waste followed by carding and needle punching. The physical activation of acrylic webs was performed by using high temperature muffle furnace at different temperatures (800, 1000 and 1200°C). These activated carbon webs were characterized by using energy dispersive X-rays, scanning electron microscopy and X-ray diffraction analysis. Further the utility of prepared activated carbon webs was checked for electromagnetic shielding ability. Activated carbon webs prepared at 800, 1000 and 1200°C showed the electromagnetic shielding effectiveness of 3.34, 26.06 and 28.29 dB at a frequency of 2.45 GHz. This behavior was attributed because of increased multiple internal reflections and stronger absorption of electromagnetic radiations in activated carbon webs. At the end these activated webs were checked for ohmic heating application. The web prepared at 800°C showed higher generation of heat (185°C) after 60 seconds at 1.5 volt.
