FERROELECTRET MULTILAYER COMPOSITE AND METHOD FOR PRODUCING A FERROELECTRET MULTILAYER COMPOSITE WITH PARALLEL TUBULAR CHANNELS |
摘要 |
<p>The present invention relates to a ferroelectret multi-layer composite (1) comprising at least two polymer films arranged one on top of the other and bonded together, wherein voids are formed between the polymer films, said voids being tubular channels, particularly running parallel to one another. The invention further provides a process for the production of a ferroelectret multi-layer composite with parallel tubular channels, and a device for carrying out the process for the production of the ferroelectret multi-layer composite according to the invention. In addition, the invention relates to a piezoelectric element containing a ferroelectret multi-layer composite according to the invention.</p> |
