Problems solved by technology

[0003] In the current existing technology, artificial composite materials are difficult to imitate and manufacture "vertical" structures similar to glaze pillars
Some research groups use ZnO nanorod arrays and polymer molecules to construct light-weight, high-strength and high-damping composite materials. Although the finished product shows certain mechanical properties, it also has many defects, such as complicated experimental operations, long preparation period, and the synthesized composite materials. Material does not have actual production potential

Abstract

The invention discloses a preparation method of a composite material with an enamel-like structure. The preparation method of the composite material with the enamel-like structure specifically comprises the following steps of weighing ethylene glycol, adding ammonium fluoride and hydrogen peroxide to prepare an electrolyte, soaking a titanium sheet for anodic oxidation to obtain an amorphous titanium oxide nanotube array, soaking the amorphous titanium oxide nanotube array in a PMMA solution, taking out the amorphous titanium oxide nanotube array, and naturally drying the amorphous titanium oxide nanotube array; dropwise adding the PMMA solution again after drying, and repeating for 4-6 times to obtain a single-layer composite material; and coating a medical binder cyanoacrylate on the surface of the tube bottom of the single-layer composite material, and rapidly transferring and hot-pressing to obtain the composite material with the enamel-like structure. According to the preparation method of the composite material with the enamel-like structure, the high-performance composite material which is easy to operate, low in cost, green, environmentally friendly, large in scale and beneficial to actual production is prepared, and the composite material has the advantages of being high in strength, high in damping and controllable in microstructure.

Description

technical field [0001] The invention relates to the technical field of preparation of an amorphous ceramic material / organic molecule composite material, and more specifically relates to a preparation method of a enamel-like structure composite material. Background technique [0002] There are many composite materials in nature that combine various superior properties, and tooth enamel is one of them. It is both hard and tough enough to cope with external impacts well. Although human skeletons, insect exoskeletons, and shells all exhibit similar excellent properties, their nanostructures differ considerably. However, the nanostructure of human, sea urchin, dinosaur and walrus enamel is basically similar, with a protein matrix wrapped between neat columns of enamel. The conserved evolution of enamel in different organisms illustrates the superiority of this structure. Therefore, the development of a composite material with enamel-like properties will have a profound impact o...
