What can be added to silicone oil to make it conductive?

Silicone oil itself is an insulating material and cannot conduct electricity, but in some cases, silicone oil can conduct electricity by adding conductive fillers. Conductive fillers mainly include metal powder, carbon black and conductive fibers. These fillers form a conductive network in silicone oil, which makes silicone oil conductive. Among them, carbon black is a commonly used conductive filler, because it has good conductivity and chemical stability, and its price is relatively low. ?

How does silicone oil conduct electricity?

1. Add conductive filler

Adding conductive filler is one of the main methods of conducting silicone oil. Adding a proper amount of conductive filler into silicone oil can form a conductive network in silicone oil, thus making silicone oil conductive. The method of adding conductive filler is simple and low cost, but attention should be paid to the selection of filler and the control of adding amount, otherwise the performance of silicone oil may be affected.

2. Composite modification

The conductivity of silicone oil can be achieved by compound modification. For example, silicone oil can be compounded with conductive materials to form conductive composite materials, thus realizing the conductivity of silicone oil. This method can optimize the conductivity and other properties of silicone oil, but the cost of composite modification is relatively high and complex process control is needed.

3. Ionic liquid modification

Ionic liquid is a kind of material with excellent conductivity. The conductivity of silicone oil can be achieved by mixing silicone oil with ionic liquid. Ionic liquids can form conductive channels in silicone oil, thus making silicone oil conductive. This method can achieve high conductivity of silicone oil, but the cost of ionic liquid is high and complex process control is needed.
