Abstract

The invention relates to a water-soluble mercaptan-terminated PEG-functionalized POSS cross-linking agent, a preparation method and applications thereof, wherein the macromolecular polymer has a structure represented by the following formula defined in the specification. According to the present invention, the water-soluble mercaptan-terminated star-shaped macromolecular polymer POSS-PEG-SH can beused as a cross-linking agent to react with a compound containing a double bond and other functional groups so as to prepare hydrolytically degradable hydrogels, enzyme-sensitive hydrogels and otherhydrogels, and due to the introduction of the polyfunctional POSS nanoparticles, a plurality of cross-linking sites can be added during the gelation so as to effectively improve the mechanical properties of the hydrogel.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a water-soluble mercaptan-capped PEG functionalized POSS crosslinking agent and a preparation method and application thereof. Background technique [0002] Hydrogels, a class of flexible polymeric materials similar to natural extracellular matrix (ECM), are widely used as tissue engineering scaffolds and drug and gene delivery matrices due to their flexibility and hydrated form. Among them, poly(ethylene glycol) (PEG) hydrogel is one of the most widely studied and widely used flexible hydrogel materials, which has good biocompatibility, hydrophilicity, biodegradability, non-immunogenic Key properties such as sex and anti-protein adsorption; can be excreted through the kidneys. However, under certain conditions, the "softness" of hydrogels has become a disadvantage, especially when the mechanical strength of hydrogels is much lower than that of certain biological tissues.
