AI Technical Summary

Technical Problem

Existing technologies cannot effectively construct a high-adhesion insulating interface for PET corona modification, resulting in low adhesion of the insulating interface, poor insulation performance, and a poor user experience for the temperature and pressure integrated sensor.

Method used

By obtaining the processing width, conveyor speed, corona power, and energy coupling coefficient of the PET substrate, the corona energy dose per unit area is calculated, the target surface energy is set for inverse solution, corona treatment is performed, and feedback correction is made based on the online surface state detection results to form an electrode layer and an insulating layer, thereby achieving a high-adhesion insulating interface.

Benefits of technology

The reliability of the insulation interface of the integrated temperature and pressure sensor was improved under humid heat, thermal cycling and bending conditions, the batch defect rate was reduced and the adhesion performance and consistency of the insulation interface were improved.

Abstract

The application is suitable for the technical field of insulation interface of temperature and pressure integrated sensor, and provides a construction method of high-adhesion insulation interface based on PET corona modification, which comprises the following steps: setting a target surface energy to obtain a target corona dose through target inverse solution, and inversely solving a target corona power or a target walking speed as a corona treatment setting value according to the target corona dose; performing corona treatment on a PET substrate, and inversely solving an error term based on an online surface state detection result to feed back and correct the corona treatment setting value; forming an electrode layer on the surface of the corona-treated PET substrate, and forming an insulation layer and a packaging layer on the electrode layer to construct a high-adhesion insulation interface; performing consistency detection on the adhesion performance and the insulation performance of the high-adhesion insulation interface, and determining that the consistency index exceeds a preset consistency index to determine that the consistency index is passed, otherwise, the corona treatment setting value is updated; thereby, the experience dependence is reduced through inverse solution, and the surface energy fluctuation is inhibited through feedback correction of the corona treatment setting value.
