Transparent composite film and flexible display devices including the same

Abstract

Described herein are articles and methods of making articles, including a transparent composite film having a fiber filler embedded in a polymer network. The polymer network of the transparent composite film is a cured, cross-linked matrix including a first and second structure segment. The structure segments may contribute or impart improved properties in the transparent composite film. The select structure segments can provide increased modulus and reduced glass transition temperature thereby allowing for a desirable balance of flexibility and rigidity in the transparent composite film. Theimproved transparent composite film is suitable for many applications including use in display devices.

Problems solved by technology

[0012] As can be seen from the above examples, to date, composite compositions designed to reduce the coefficient of thermal expansion and improve other physical and thermal properties have been deficient for one or more of the following reasons: (1) the use or generation of organic Molecules or water molecules, which are difficult to completely remove from composite products, which can damage product performance, such as long-term stability and dimensional stability, (2) require long-term and high-temperature treatment to complete chemical reactions, which increases costs and is not conducive to yield, and in some cases lead to discoloration, (3) some handling required is incompatible with roll-to-roll manufacturing, which is disadvantageous in terms of cost and availability, and (4) the use of high glass transition temperature Rigid resin matrix, which can lead to limited flexibility of composite products, product discoloration, cracking and delamination at the interface between resin matrix and glass filler due to insufficient adhesion
