Description

【Technical field】 [0001] The invention relates to the technical field of thin films, in particular to a polymer thin film polarization system. 【Background technique】 [0002] Polarization is an important step in the processing of thin film materials. The main purpose is to make the molecular dipole moments of disordered orientation in the thin film materials uniformly oriented along a specific direction (such as the direction of the polarized electric field), so that the thin film materials have piezoelectric properties. [0003] Thin-film polarization usually directly places the thin-film material between the electrodes, and uses the high-voltage electric field generated by the electrodes to complete the polarization. This method is very easy to break down the thin-film material. In particular, some polymer thin film materials are directly formed on the surface of electronic devices. Direct polarization in a high-voltage electric field is also likely to cause damage to the ...
