Polyurethane/polyaniline/nanosilica composites were prepared. The electronic resistance of the polyurethane was decreased
while the strength of the polyurethane was increased. As a result
the antistatic and mechanic properties of polyurethane were improved with the doping of polyaniline and nanosilica.
Antistatic and strength properties are of vital importance for polyurethane rubber used in moving parts of many industrial instruments. Herein
polyurethane was composited with polyaniline and nanosilica based on
in situ
synthesis of polymer and physical mixing of these fillers to reach desired antistatic and mechanical properties. Chemical
morphological and thermal properties of the polyurethane/polyaniline/nanosilica composites were studied. The electrical resistivity of the composite decreased from 1.1×10
6
MΩ to 7.6×10
4
MΩ as a result of the addition of 4% polyaniline. The tensile strength and elongation at break of the polyurethane composites improved by nearly 300% and 100%
respectively
when compared with those of the neat polyurethane. The electronic resistance of PU/PANI/NS ternary is low enough for its antistatic property and decreases with the increase of the added nanosilica
which is unexpectedly and rather significant. Our results would shed light on the development of antistatic PU with excellent mechanical performance.
