Prepolymer of biomedical material

Abstract

The invention relates to a prepolymer of a biomedical material, having the following chemical formula shown in the specification, wherein X1 is an aliphatic compound or an aromatic compound, X3 is an alkene-containing functional group compound, and X2 is a siloxane compound having the following chemical formula. In one embodiment of the invention, n is between 1 and 20, m is between 10 and 20 and y is between 1 and 7.

Description

technical field The invention relates to a prepolymer of a biomedical material, in particular to a prepolymer of a biomedical material which is breathable, oxygen permeable and moisturizing. Background technique The suitability of materials for biomedical devices depends on several factors, including the material's moisture retention, oxygen permeability, adhesiveness or reactivity with other biological materials such as proteins and lipids. Generally speaking, medical personnel currently use gauze as a prepolymer for wound dressings to avoid wound exposure infection. However, the disadvantage of gauze is that it cannot prevent moisture from volatilizing from the wound surface, and it is easy to destroy the incrustation of the mouth when renewing the dressing of the wound. Recently, researchers have developed dressings made of polymer materials (such as polymer materials containing siloxane), which can improve the shortcomings of gauze. In addition, in ophthalmic applicati...
