Magnetic composite

摘要

The invention relates to a polymer composite having magnetic properties that are enhanced or increased in the composite. Such properties include color, thermal conductivity, electrical conductivity, density, improved malleability and ductility viscoelastic and thermoplastic or injection molding properties.

1. A magnetic particle and polymer viscoelastic composite comprising:
(a) a magnetic particle consisting of a ferrite having an exterior coating of about 0.005 to 8 wt. %, based on the composite, of an interfacial modifier, the magnetic particle having a particle size greater than about 1 micron, a particle size distribution such that there are greater than about 5 wt. % of magnetic particles in the range of 1 to 1000 microns to form the composite; and (b) a thermoplastic polymer phase;wherein the viscoelastic composite has a tensile elongation of about at least 5%.
