Abstract

A method for polarizing a polymer film is disclosed. An ambient gas above a polymer film under the action of a first electric field is ionized, the ambient gas accumulates on the second surface of the polymer film through the second electric field, an organic electric field in the film thickness direction is formed in the molecular thin film, and the polymer film is polarized. The polymer film polarization method can avoid the breakdown of the polymer film, effectively improve the production rate of the polarized film, can achieve large-scale production; and the resulting polarized film has a strong piezoelectric effect and longer Service life. The present invention also provides a polarizing film prepared by the above-described method of polymer film polarization, which has a strong piezoelectric effect and a long service life. The present invention also provides an electronic device comprising a substrate and a polarizing film as described above.

Description

【Technical field】 [0001] The invention relates to the field of thin film technology, in particular to a polymer thin film polarization method, a polarization film and an electronic device. 【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 electri...
