摘要
Abstract
To research the adhesion strength between polyimide(PI)solution and TFT substrate,a series of polyimide solutions with different viscosity were prepared to research its adhesion strength with TFT substrate by preparing a 5-layer adhesion sample.The results demonstrated that the adhesion strength between polyimide solution and TFT substrate increased at first and then decreased when the PI solution viscosity decreased from 86 CP to 15 CP.The long contact distance and small contact area between PI membrane and TFT substrate were the key factor to achieve high adhesion strength when PI solution viscosity was greater than 37 CP.However,when its viscosity was less than 37 CP,the cohesive energy of PI solution became the key factor to achieve high adhesion strength.When PI solution viscosity was 37 CP,it could meet the production requirements of low viscosity and high adhesion strength with TFT substrate.关键词
