| description |
Thermoplastic natural rubber (TPNR) was prepared by melt-blending of polypropylene
(PP) and natural rubber (NR) in weight percentage ratio of 70:30 using internal
Rheomixer. Sample of Yttrium Iron Garnet (Y3FesOI2) filled TPNR was prepared at a
fixed TPNR content (70% of the total weight). The effect of YIG content with two
thicknesses on dielectric constant (Ɛr =Ɛ'r - jƐ"r) and loss tangent (tan [δ = Ɛ"/Ɛ')
were studied. Dielectric constant and loss tangent were analyzed using PNA-L Network
Analyzer in the frequency range of (8-12 GHz). The homogeneity of sample was
verified using Pyris 1 Thermogravimetric Analyzer (Perkin Elmer). The samples
prepared were pure TPNR, 2 mm and 5 mm YIG filled TPNR. The dielectric constant
for 5 mm sample was higher than that of the 2 mm. On the other hand, the loss tangent
for 2 mm sample was lower than that of 5 mm YIG filled TPNR. This composite shows
the value of dielectric constant and loss tangent at the X-band. Hence, this research will
help in increasing the value of Malaysian second crop which is natural rubber |
