Abstract: A silicone-free thermal interface for placement along a thermal dissipation pathway is provided for long-term durability. The thermal interface is formed from a multi-part composition and cured in place to obtain a conformable coating with low durometer hardness, which is maintained by a non-crosslinked diluent product formed from a reactive diluent system.

Abstract: Oligomer-grafted nanofiller compositions and composites including oligomer-grafted nanofillers are disclosed. An oligomer-grafted nanofiller composition for disposition in a polymer matrix, the polymeric matrix comprising polymers derived from a plurality of polymerizable units, can include a nanoparticle, one or more coupling groups bonded to the nanoparticle; and one or more oligomers bonded to the one or more coupling groups. In an embodiment the oligomer is derived from two or more polymerizable units, at least one polymerizable unit being at least substantially similar to at least one of the polymerizable units of the polymer matrix. In another embodiment the oligomer comprises two or more polymerizable units and improves dispersion, interfacial strength, or both dispersion and interfacial strength between the nano-particle and the polymer matrix. Composites and methods are also disclosed.

Abstract: The invention concerns nanofiller composition comprising (i) a nanoparticle; (ii) a plurality of coupling groups bonded to the nanoparticle; (iii) one or more (a) oligomers or (b) organic isocyanate residues bonded to the one or more coupling groups; and, optionally, (iv) one or more dispersing moieties that facilitate dispersion of the nanoparticle bonded to one or more of the coupling groups or organic isocyanate residues; as well as laminates comprising such nanoparticles in at least one layer.
