| 摘要 |
The present invention provides a polymer laminar composite including a first layer and a second layer at least partially in contact with the first layer. The first layer includes a polyurethane polymer which is the reaction product of a polyisocyanate A) and/or a polyisocyanate prepolymer B) with an at least difunctional, isocyanate-group-reactive compound C) and a monomeric, monofunctional aromatic alcohol. The second layer includes polymeric thiophene of the formula (I), substituted at the 3 and/or 4 position: and polystyrene sulfonate. 2-Hydroxymethyl-3,4-ethylene dioxythiophene is preferably used for the first layer and poly(3,4-ethylene dioxythiophene) for the second layer. The invention further relates to a process for producing such a laminar composite, as well as an electromechanical converter containing this laminar composite. |
