Multi-crosslinked gel system and products, preparation methods, and uses thereof

Abstract

The present application relates to a multi-crosslinked gel system and a product thereof, a preparation method, and a use. Particularly provided is a preparation method for the multi-crosslinked gel system. The preparation method comprises: under a condition suitable for crosslinking, enabling a polymer compound to undergo a first crosslinking reaction in the presence of a long-chain crosslinking agent to obtain a preliminarily crosslinked gel network; and swelling, precipitating and redissolving the preliminarily crosslinked gel network to form a preliminarily crosslinked gel; under a condition suitable for crosslinking, enabling the preliminarily cross-linked gel to undergo a second crosslinking reaction in the presence of a short-chain crosslinking agent and/or a condensing agent to obtain a secondarily crosslinked gel network; and swelling, precipitating and redissolving the secondarily crosslinked gel network to form a multi-crosslinked gel system. Also provided is a wide use of the multi-crosslinked gel system and the product thereof in medical treatment, beauty, production and daily chemicals.
