Processing of nano
boron carbide reinforced flexible polymer composites with improved shielding
properties
Aims:
The main objective of the current research is to develop light-weight and flexible
electromagnetic shielding materials with improved properties using nano/mikro
boron carbide dispersed into polymer based matrices after surface modification.
Methods:
Nano/micro
boron carbide particles with various morphologies were synthesized by sol-gel
techniques and the obtained particles were surface modified with different
functional groups. After mixing the particles with different polymers using
high shear mixer, shielding composite plates were shaped using injection
moulding and warm pressing.
Results:
It
was shown that sol-gel technique was able to produce boron carbide particles
with controlled morphology and better shielding properties could be obtained
using these particles within polymeric matrices leading to the formation of
flexible composites.
Conclusions:
Overall,
it was found that light-weight and effective shielding materials could be
obtained using boron carbide particles dispersed within polymeric matrices.
Surface modification of the particles is critical for good dispersion and hence
to get better final properties. The concentration of the reinforcing particles
also affects the properties in terms of energy absorption and shielding.
