23 Jul Multilayer aquagel, and preparation method and application thereof
Abstract
The invention relates to a high polymer aquagel, particularly a multilayer aquagel, and a preparation method and application thereof. The invention provides a multilayer aquagel with controllable shape and structure and onion pattern, and a preparation method and application thereof. The multilayer aquagel with onion pattern is composed of a gel core template and a multilayer film aquagel coated outside the gel core template. The preparation method comprises the following steps: 1) dissolving a material for preparing the gel core, and gelating to obtain the gel core template; 2) impregnating the gel core template in a crosslinking agent water solution, so that the gel core template adsorbs the crosslinking agent; 3) impregnating the gel core template with adsorbed crosslinking agent in a water-soluble macromolecular solution to obtain a monolayer-film-coated aquagel; and 4) repeating the step 2) and step 3) to obtain the product. The materials have wide sources, the shape and size of the template can be designed freely, and the shape of the multilayer aquagel can be designed as required; and the microstructure of each gel layer is a large-aperture network structure, so that the aquagel has wide application prospects in medicine embedment, medicine slow release and tissue engineering.
