Title:
PREPARATION METHOD FOR FLUORESCENT AND TRANSPARENT COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2021/223336
Kind Code:
A1
Abstract:
A preparation method for a fluorescent and transparent composite material, comprising: (1) selecting a crab shell or crab shell piece having a complete form, washing, and saving in deionized water for later use; (2) sequentially using a low-concentration acid solution, a low-concentration alkaline solution, and an ethanol solution to immerse the complete crab shell or crab shell piece until completely removing calcium carbonate, proteins, lipids, and a pigment matrix, and saving the treated crab shell or crab shell piece in anhydrous ethanol for later use; (3) uniformly dispersing a fluorescent material in a polymer monomer by means of thermomechanical stirring, and then performing polymerization to obtain a polymer; and (4) taking out the treated crab shell or crab shell piece, immersing in the polymer obtained at step (3), performing vacuum pumping in a vacuum drying box and keeping pressure for 15 minutes, repeating three times, taking out the crab shell or crab shell piece and wrapping same with a tin foil, and performing isothermal curing. The prepared fluorescent and transparent composite material not only is high in light transmittance, but also has a complete crab shell form; and the addition of fluorescent powder makes a transparent crab shell present different colors under the irradiation of light and has little influence on the light transmittance.
