A photo-curable composition for use in additive manufacturing, said composition comprising: a) at least one photocurable monomer or oligomer; b) a photoinitiator for polymerization of the monomer; and, from 0.01 to 1 wt. %, based on the weight of the composition, of c) CNS-derived materials. Following polymerization, the resulting polymerized composition has a volume resistivity no greater than 10ohm·cm.

Conductive photo-curable compositions for additive manufacturing

A composite polymer composition comprising partially crystallized carbon black. The composition exhibits superior thermal transfer properties in plastic formulations. The polymer precursor exhibits excellent rheology when compared to similar compositions comprising traditional carbon blacks. The composite polymers provide for higher loading of more thermally conductive carbon blacks in a variety of composite polymer compositions.

Thermally conductive polymer compositions containing carbon black

Disclosed herein are elastomer compounds comprising: at least one elastomer that is resistant to heat for 70 h at 100&#xb0; C. such that the at least one elastomer exhibits at least one of the following properties selected from: (a) a change in durometer hardness of no more than 15 points, (b) a change in tensile strength of no more than 40%, and (c) a change in ultimate elongation of no more than 40% The elastomer compound further comprises at least one graphene-based material present in an amount ranging from 0.01 phr to 30 phr relative to the at least one elastomer and at least one carbon black present in an amount ranging from 15 phr to 150 phr relative to the at least one elastomer. Also disclosed are methods of making such compounds, and articles comprising elastomer compounds.
