Carbon Extraction from Rice Husk and its Application as a Microwave Adsorbent

Abstract:

The purpose of this research is to observe the influence of carbon from rice husk charcoal composition at Unsaturated Polyester Resin/Carbon (UPR/C) composite as electromagnetic wave absorber. In this research, carbon has been synthesized from rice husk charcoal. Characterization with SEM-EDX and FT-IR showed that the carbon consists of C, O, and Si atoms. Characterization with XRD showed that carbon from rice husk charcoal is amorf with the maximum value of 2θ is 22,86^o, respectively. Carbon from rice husk charcoal then is used as a composite filler with UPR as the composite matrix with ratio filler/matrix such as 5:95; 10:90; 15:85; 20:80 and 25:75 (%w/w). Characterization with VNA is done at the frequency range of 8-12 GHz. It has been found that the composite which contains filler carbon 20% exhibits optimum reflection loss of peaks with-19,5909 dB at 10.60 GHz. The result showed that inside UPR/C composite can be used as an electromagnetic wave absorber.
