| 摘要 |
<p>The invention relates to a polymer sheet material with piezoelectric properties comprising PVDF or co-polymers and method for manufacturing a polymer sheet material with piezoelectric properties comprising PVDF or co-polymers thereof by
a) subjecting the polymer sheet material (1) to an electric field (E) between two electrodes (21, 22), in particular a corona arrangement,
b) while subjecting the polymer sheet material (1) at the same time to a temperature treatment with a temperature of above 100°C,
c) during a) and b) the polymer sheet material (1) is positioned on a treatment surface (20),
d) wherein the treatment surface (20) comprises structural elements (3) for generating inhomogeneity in the electric field (E).</p> |
