▎ 摘  要

NOVELTY - Preparing double network airgel, comprises (i) mixing natural polymers, synthetic polymers, one-dimensional materials or two-dimensional materials with methacrylic anhydride gelatin in a solvent to form a polymer solution, and (ii) mixing the polymer solution with the blue light initiator and performing photocuring to obtain the double-network airgel. USE - The method is useful for preparing double-mesh gas gel, which is useful in tissue engineering scaffold (claimed), space material, heat insulating material and energy storage period. ADVANTAGE - The method is simple and easy to operate, the aperture and the mechanical adjustable change of the prepared double-net-shaped gas gel are good in biocompatibility. The natural polymer is preferably chitosan from the group consisting of the two materials as natural polymer, with excellent biological compatibility and biological degradability. The synthetic polymer comprises polyethylene glycol diacrylate (PEGDA). DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: double-network airgel prepared by above-mentioned method; and tissue engineering scaffold comprising double mesh aerogel.
