In accordance with the present invention, novel superparamagnetic magneto-dielectric polymer nanocomposites are synthesized using a novel process. The tunability of the dielectric/magnetic properties demonstrated by this novel highly-viscous solvent-free polymer nanocomposite that is amenable to building 3D electromagnetic structures/devices by using processes such as 3D printing, compression molding or injection molding, when an external DC magnetic field is applied, exceeds what has been previously reported for magneto-dielectric polymer nanocomposite materials.

Disclosed is an adhesive for an adhesive layer of a fixing member including a substantially cylindrical substrate, an elastic layer around the substrate, a surface layer covering the elastic layer, and the adhesive layer between the elastic layer and the surface layer. The adhesive contains a dialkylpolyorganosiloxane having crosslinking groups and a dialkylpolyorganosiloxane having vinyl groups. The molar ratio of the crosslinking groups to the vinyl groups in the adhesive is about 1.1 to about 4.

An inductively curable thermoset compositions comprising a thermoset resin and, dispersed therein, susceptor particles and surface modified silica particles is described.

A fluororubber composition in which fluororubber is compounded with triiron tetraoxide having a BET specific surface area of 4.0 m.sup.2/g or less at a ratio of 7.0 vol % or more as a volume fraction. A crosslinked product obtained by the fluororubber composition according to the present invention can be detected 1 mm pieces thereof by using a metal detector ND-840, produced by Nissin Electronics Co., Ltd., under the detection sensitivity conditions (Fe: 0.6 in diameter, SUS: 1.5 in diameter). Further, the compression set of the crosslinked product using an O-ring at 175 C. after 70 hours is 21% or less, and thus the crosslinked product can be effectively used for gaskets, O-rings, and the like for food production facilities, food machinery, automobiles, etc.

A patterned surface structure formed from a ferrofluidic polymer resin having a plurality of magnetic nanoparticles. The polymer resin is patterned with a magnetic field that is applied to the ferrofluidic polymer resin during curing. The ferrofluidic polymer resin may be cast over a non-magnetic planar substrate. A magnetic field is applied to the ferrofluidic polymer resin to induce a pattern in a surface of the ferrofluidic polymer resin. The patterned ferrofluidic polymer resin is then cured to form the permanently patterned surface.
