MATERIALS PROPERTIES AND SYNTHESIS

Ionic Bondinge.g. saltCe- e-Na+Cl-CMelting PointsIonic bonding is often stronger than metallic bondingCeramics tend to have higher melting points than metalsCovalent bonds can also be extremely strongCovalently bonded materials may also have higher meltingpoints than metals, e.g. diamondHowev[r]

The present paper reveals the synthesis of polyaniline, polyaniline nanoparticles and polyaniline composite. Improvement of polyaniline properties can be achieved either by forming composites and nanocomposites of aniline, or blends with commercially available polymers or inorganic materials which o[r]
