Abstract:
Rubber–nickel nanocomposites were synthesized by incorporating
freshly prepared nanometric nickel particles in two different matrices namely natural
rubber and neoprene rubber according to specific recipes for various loadings of
nano nickel and the cure characteristics of these composites were evaluated. The
maximum torque values register an increase with the increase in loading of nickel in
both composites and this is attributed to the non-interacting nature of nickel
nanoparticles with rubber matrices. The cure time of natural rubber composites
decreases with increase in the content of nickel, and in neoprene rubber cure, time
increases with increase in filler content. In natural rubber, the curing reaction seems
to be activated by the presence of nickel particles. The magnetization studies of the
composites reveal that the magnetic properties of nickel are retained in the composite
samples. The elastic modulus of natural rubber and neoprene rubber are
largely improved by the incorporation of nickel particles
