A material that gives the cables three times lower conductivity

Caption

The basis of the new material is polyethylene, which is already used for insulation in existing HVDC cables. Now, by adding very small amounts – 5 parts per million – of the conjugated polymer known as poly(3-hexylthiophene), the researchers were able to lower the electrical conductivity by up to three times.
