There is a dopant for the vhb 4910 actuator tapes that have acetylene black or carbon black which is carbon grease (carbon black + pdms) commercially, I am making a robotic actuator but I don't know what is the difference at a chemical level between carbon black and carbon and why In some papers there is talk of a negative intrusive charge which, when placed as electrodes, having a thin layer of vhb 4910 in the middle, these electrodes are attracted by the high voltage that is applied, causing the vhb to be crushed, stretching or changing shape by attraction but I don't know why that dopant is the only one that works for the vhb 4910 and because it has that intrinsic charge or what is that intrinsic charge
