Abstract

The present invention provides a polymer molecular film, a photo-electronic element comprising the same and method for manufacturing the same. The polymer molecular film of the invention is formed via a deformation process on a substrate. Particularly, the polymer molecular film includes a plurality of conjugated polymers, therein at least one of the conjugated polymers has a stretched molecular structure. As a result, the photo-electronic element having said polymer molecular film performs with good lighting or power generating efficiency.

First claim

What is claimed is:

1. A method of manufacturing a polymer molecular film, comprising the steps of:
applying a conjugated polymeric material on a substrate to form a polymeric material layer; and
un-stabilizing the conjugated polymeric material layer by a dewetting process without being stretched additionally by mechanical forces to form the polymer molecular film; wherein at least one conjugated polymer of the polymer molecular film has a stretched molecular structure therein.

2. The method of claim 1 , wherein the step of un-stabilizing the polymeric material layer to form the polymer molecular film further comprises:
heating the polymeric material layer until the temperature of the polymeric material layer is higher than the glass transition temperature of the polymeric material layer.

3. The method of claim 1 , wherein the polymer molecular film further comprises a plurality of protrusion areas and at least one indentation area, wherein at least one conjugated polymer of the stretched molecular structure is located in the indentation area.

4. The method of claim 3 , further comprising:
removing the parts of the protrusion areas which are higher than the indentation areas, such that the polymer molecular film has a flat surface.

5. The method of claim 1 , wherein the conjugated polymer is selected from the group consisting of poly[1-methoxy-4-(2′-ethyl-hexyloxy)-2,5-phenylene vinylene] (MEH-PPV), polythiophene and polyphenylene.
