Abstract

The invention discloses a preparation method of an optical clear electro-driven shape memory polymer film and relates to a preparation method of a shape memory polymer film. In order to solve the problems of driving by direct heating and low light transmittance of existing shape memory polyimide, the method comprises the steps of: 1, dispensing a transparent conductive coating solution on a support substrate to form the support substrate with a transparent conductive coating, 2, coating the upper surface of the transparent conductive coating with a precursor solution of shape memory polyimide,3, performing thermal imidization on the precursor solution, and 4, performing demolding and drying. The optical clear electro-driven shape memory polymer film prepared by the method is high in lighttransmittance and good in mechanical property and adopts non-contact electro-driving. The preparation method is applicable to preparing the optical clear electro-driven shape memory polymer film.

Description

technical field [0001] The invention relates to a preparation method of a shape memory polymer film. Background technique [0002] Shape memory polymer (Shape Memory Polymer) is a new type of functional polymer material, which can make corresponding responses when it is stimulated by temperature, light, electricity, solvent, magnetism, etc., so as to return to the preset shape. shape. Shape memory polymer not only has a large amount of deformation, is easy to form, and is easy to adjust the shape response temperature, but also has the advantages of heat preservation, good insulation, no rust, easy coloring, printable, light weight and low price, etc. , flexible electronics (Flexible electronics), optoelectronic products and other fields have broad application prospects. [0003] The shape memory polyimide prepared by the existing method has the problems of deep color and low light transmittance; [0004] The reason for the deep color of the shape memory polyimide prepared...
