Abstract

An Electromagnetic (EM) composite based detector filled with ZnO and
carbon nanotubes (CNTs) nanoparticles was developed. This work premise deals
with synthesis of ZnO using self combustion and sol-gel techniques. These two
techniques were chosen in order to compare which technique will give a better
result of ZnO nano structure. The mixture consists of 1 Ograms of zinc (II) nitrate,
Zn(N03)2.6H20 salt was dissolved in 50mL of nitric acid, HN03 and stirred at
250 r.p.m continuously for 24 hours. The mixture was then gradually heated for
every 15 minutes until it combusted at 11 o•c for the self combustion technique.
For sol gel technique, the dissolved mixture was heated at 40°C, 50°C, 6o•c and
1o•t until the gelatin is formed. After drying process, the as-prepared samples
were annealed at l50°C and 250 •c for 2 hour for each technique. Morphology
and phase characteristic was covered in the characterization part.
Characterizations were done by using X-Ray Diffractions (XRD), Energy
Dispersion X-ray Spectroscopy (EI>X) and Field Emission Scanning Electron
Microscope (FESEM). Single phase crystal nano structure of ZnO was
successfully obtained. The morphology of ZnO is shown in the nano-size
dimension. These samples were used as additive to the PV A composite detector.
The PV A composite was prepared using casting method. The result from the
testing and validation part shows that the presence of ZnO and CNTs as a filler in
the PV A composite detector can enhance the detection up to 70%.
