Abstract

The invention provides a preparation method of a ductile substrate material. The preparation method specifically comprises the following steps of drying periostracum cicadae to be at the constant weight and then crushing the periostracum cicadae to obtain periostracum cicadae powder; transferring the periostracum cicadae powder into a mixed solution of sodium iminodisuccinate, potassium persulfateand hydrogen peroxide, carrying out sealing, heating and continuous stirring, filtering a product, and washing filter residues with deionized water to be neutral; transferring the filter residues into an acetic acid solution, carrying out grinding and ultrasonic treatment, carrying out centrifuging to obtain supernate; and diluting the supernate with the deionized water, and evaporating part of the water to prepare hydrogel. The ductile substrate material is prepared by taking the periostracum cicadae as raw materials, performing treatment by a specific physicochemical method to obtain a novel nanoscale and degradable biotechnology substrate material subjected to chemical modification, and then performing a film forming process. The ductile substrate material has the advantages of being environment-friendly, low in cost and the like. A film material prepared from the ductile substrate material shows very good visible light transmittance and ductility, and still has relatively high visible light transmittance, relatively low color changes and relatively small crimpness in a special environment after substrate formation.

Description

technical field [0001] The present invention relates to a substrate material, in particular to a method for preparing a ductile substrate material. Background technique [0002] The display device can display the visualized data. A display device may include a substrate including a display area and a non-display area. In the display area, the gate lines and the data lines may be electrically separated from each other and intersections between the gate lines and the data lines may define a plurality of pixel areas in the display area. In the display area, thin film transistors and pixel electrodes electrically connected to the thin film transistors may be connected to corresponding pixel areas. In the non-display area, various conductive layers such as wirings that transmit electrical signals to the display area may be arranged. The flexible display device may include a curved portion or a reduced foldable non-display area. Flexible display devices may include ductile fle...
