Abstract

The present invention provides a flexible substrate for a display panel. The flexible substrate comprises: a composite film comprising SiO2 nanotubes / polymer matrix, wherein the polymer matrix is polyimide, polyetherimide, polyphenylene sulfide, polyaryl ester, or any combination thereof; Wherein the concentration of the SiO2 nanotubes in the composite film varies in a gradient in an x-axis direction which is a direction perpendicular to the surface of the composite film.

Description

【Technical field】 [0001] The present invention relates to the technical field of display panels, in particular to a flexible substrate for a display panel and a manufacturing method thereof. 【Background technique】 [0002] With the development of the display technology of the display panel, the requirements for the flexible substrate used for the display panel are becoming more and more stringent. Compared with glass substrates, polymer substrates are light and soft, which is in line with the current development trend of flexible substrates and has naturally been widely used. However, due to some material properties of the polymer substrate, the development of using the polymer substrate in the display panel still encounters great difficulties. In particular, in order to be able to replace traditional glass substrates, manufacturers have put forward higher requirements for the substrate's optical transparency, mechanical properties, water and oxygen barrier properties, and ...
