Embodiment 1
[0060] Graphene carbon particles were produced using a DC thermal plasma reactor system. The main reactor system consisted of a DC plasma torch (commercially available as a model SG-100 plasma torch from Praxair Technology, Inc., Danbury, Connecticut) into which 60 standard liters per minute of argon carrier gas and 26 kilowatts of power were delivered. to the torch for operation. A methane precursor gas (commercially available from Airgas Great Lakes, Independent, Ohio) was fed to the reactor at a rate of 5 standard liters per minute about 0.5 inches downstream from the outlet of the plasma torch. After the 14 inch long reactor section, multiple quench injection ports were provided, including six 1 / 8 inch diameter nozzles located 60° radially apart. Quench argon was injected at a rate of 185 standard liters per minute through the quench stream injection port. The resulting particles were collected in a bag filter. The total solid material collected was 75% by weight of the...
Embodiment 2
[0062] In this example, resin mixture A used in all experiments was prepared first. Permapol P3.1e, Permapol L56086 (commercially available from PRC-DeSoto International, Inc.), HB-40 plasticizer (commercially available from Solutia Inc.), DABCO 33LV amine catalyst were used in the order and amounts listed in Table 1. (commercially available from Huntsman), and tung oil (commercially available from Alnor Oil Company, Inc.) were added to a "Max 300" (FlackTek) canister. These materials were mixed by a DAC 600.1 FVZ mixer (FlackTek) for 45 seconds. Resin Mixture A was then added portionwise to a "Max 100" (FlackTek) jar and graphene carbon particles were added on top of each sample, mixed on a DAC 600.1 FVZ mixer for 70 seconds. The samples were allowed to cool to room temperature before adding the manganese dioxide accelerator, and the samples were mixed again in the DAC 600.1 FVZ mixer for 35 seconds. All amounts are listed in Table 2. The mixed sample was immediately poure...
Embodiment 3
[0069] In this example, resin mixture A used in all experiments was prepared first. All materials (listed in Table 3) were combined as described in Example 2. Resin mixture A was added portionwise to a "Max 200" jar (FlackTek) and graphene was added on top. The samples were mixed as described in Example 2. Sipernat D13 precipitated silica (Evonik) and calcium carbonate (Solvay) were added to their respective samples at 2% each (based on resin mixture A) until a viscosity of approximately 9000 poise (not measured) was reached. The samples were mixed for 35 seconds between each addition. All amounts are listed in Table 4. The samples were allowed to cool to room temperature and remixed as described in Example 2 prior to the addition of the manganese dioxide promoter. Immediately pour the sample into the 1 / 8 inch thick Teflon molds and cured at room temperature for two weeks. The cured cake was removed from the mold, and the resistivity was measured using a resistivity m...
