23 Jul Preparation method of high-strength dual-mesh nano-meter titanium dioxide composite hydrogel
Abstract
The invention discloses a preparation method of a high-strength dual-mesh nano-meter titanium dioxide composite hydrogel. The preparation method comprises the following steps: preparing a nanometer TiO2 water solution by using cooled boiling distilled water, dissolving sodium alginate, acrylamide, a crosslinking agent, an initiator and a catalyst in the TiO2 water solution, rapidly transferring the prepared solution into a glass mould, placing the sealed mould in an environment of a temperature of 45-55 DEG C for performing an insulation reactor for 2-6h; and taking hydrogel formed in the mould out and then dissolving the hydrogel in a CaCl2 water solution with a concentration of 0.1-1M for 2-6h, and taking out to obtain the high-strength dual-mesh nano-meter titanium dioxide composite hydrogel. Compared with a conventional hydrogel, the high-strength dual-mesh nano-meter titanium dioxide composite hydrogel disclosed by the invention is relatively high in strength and elongation so as to meet application demands of the high-strength dual-mesh nano-meter titanium dioxide composite hydrogel on aspects of human body cartilage repair, tissue engineering and the like.
