Abstract

The invention discloses a method for preparing a flexible screen transparent substrate film by utilizing lobster shells and relates to the technical field of flexible screen transparent substrate filmpreparation methods. The method comprises the following steps of 1, drying the lobster shells; 2, crushing the lobster shells; 3, boiling and refluxing the lobster shells with KOH for 2 days; 4, soaking the lobster shells with hydrochloric acid and stirring the lobster shells for 2 days; 5, refluxing the lobster shells with absolute ethyl alcohol for 5 hours; 6, washing the lobster shells to be neutral by using deionized water; 7, preparing a mixture according to a mass of lobster shell particles to volume of an aminotrimethylene sodium phosphate solution ratio of 1 grams to 20 milliliters, and stirring the mixture for 2 days; 8, performing filtering to obtain filter residues, and washing the filter residues to be neutral by using the deionized water; 9, putting the filter residues into an acetic acid solution with a pH of 2-3 for gamma ray irradiation, and carrying out centrifuging for 30 minutes; and 10, picking centrifuged supernatant, diluting the centrifuged supernatant with thedeionized water, and evaporating the centrifuged supernatant to dryness to finally obtain the flexible screen transparent substrate film. The method for preparing the flexible screen transparent substrate film by utilizing lobster shells is low in cost.

Description

technical field [0001] The invention belongs to the technical field of preparation methods of transparent substrate films for flexible screens, and in particular relates to a method for preparing transparent substrate films for flexible screens by using lobster shells. Background technique [0002] Compared with traditional liquid crystal displays, organic flexible screens have many advantages, such as lower energy consumption, thinner and lighter volume, longer battery life, and longer service life. As a new technology, organic flexible screen technology is expected to be widely used in high-tech products such as mobile phones, LCD TVs, computers, automobiles and wearable smart devices in the next 3 to 5 years. Organic transparent substrates are important components of organic flexible screens. Its traditional preparation raw material is nanoscale cellulose material. However, the cost of nanoscale cellulose materials is relatively high. Contents of the invention [000...
