Abstract

The present invention relates to an epoxy crosslinking agent and its preparation and application in preparing biodegradable material. The degrading rate and mechanical strength of the biodegradable material are regulated via regulating the molecular weight and amount of the crosslinking agent, so that the degrading rate of the material is matched with the tissue forming rate. The degraded productof the material has no toxicity for cell and no negative effect on tissue, and the cell affinity of the material can promote the adsorption of the cell tissue on the material surface.

Description

technical field

[0001] The present invention relates to biodegradable epoxy-based crosslinkers.

[0002] The invention also relates to a preparation method of the epoxy-based crosslinking agent.

[0003] The invention also relates to the application of the epoxy-based crosslinking agent in the preparation of biodegradable materials. Background technique

[0004] Biodegradable materials mainly include biodegradable films and biodegradable scaffold materials. At present, almost all degradable materials such as photodegradable materials studied at home and abroad are made of polyethylene as the matrix material through appropriate modification, and its residual film will cause harm to crops and water resources if it remains in the soil for a long time. If the photosensitive group is introduced into the polymer chain, the pollution problem of degradation products will be better solved, but it is also difficult to popularize due to problems such as processing and production. As...
