A curable fluorine-containing elastomer compositions herein have at least one curable fluoropolymer having at least one fluorinated monomer and at least one fluorine-containing cure site monomer comprising at least one cure site; at least one curative; and microdiamond particles having an average particle size greater than 0.1 microns to about 100 microns. Such compositions may be fluorinated or perfluorinated. Articles formed from the compositions herein may be used at high service temperatures, and exhibit one or more of reduced particulation, reduced high-temperature compression set values, reduced sticking force, enhanced resistance to fluorine-based plasma, oxygen-based plasma, hydrogen-based plasma, and combinations thereof, and improved physical properties.

Compositions of at least one matrix polymer that may be a thermoplastic and/or curable polymer having at least one functional group for crosslinking for use in forming articles are disclosed as well as methods for making such articles, wherein the compositions and methods include a carbon nanostructure additive that is three-dimensional, branched and crosslinked. The resulting articles can in one embodiment provide a volume resistivity level of about 0.5 ohm-cm or less which are useful in applications requiring conductivity sufficient to provide electromagnetic interference shielding and/or radio frequency interference shielding. Other articles formed using compositions disclosed herein in other embodiments can demonstrate dissipative and/or quantum tunneling effects and so are useful as self-sensing pressure sensitive articles, such as self-sensing seals.
