Abstract

The invention relates to a preparation method of a low-temperature photopolymerization catalyst for a biological bonding agent, and belongs to the technical field of a biological material. According to the technical scheme, benzophenone and methyl-beta-cyclodextrin materials are compounded to form a grafting substrate; the cyclodextrin is a kind of tubular compound formed by connecting seven glucose molecules through glucosidic bonds, and realize the characteristics of hydrophobic inner cavities and hydrophilic outsides, so that the cyclodextrin can form clathrate compounds with various organic and inorganic molecules through Van der Waals' force, hydrophobic mutual action force, subject-object molecule matching action and the like; a photocatalyst is filled to from a wall material for preparing a photocatalyst wall material; the temperature performance of the material is effectively improved; in addition, the photocatalyst material is filled into the material; the formed wall materialis used for preparing the photocatalyst wall material with excellent performance; paraffin is clathrated; a phase change microcapsule structure material is prepared; the polymerization temperature inthe polymerization reaction process of the material is reduced; the temperature requirement and the use efficiency of biological materials in the polymerization process can be improved.

Description

technical field [0001] The invention relates to a preparation method of a low-temperature photopolymerization catalyst for biological adhesives, belonging to the technical field of biological materials. Background technique [0002] Bioadhesives refer to medical materials used in the medical field, especially in surgical operations, to bond tissue parts of living bodies. According to different tissue parts, there are many options for bioadhesives, which makes bioadhesives receive extensive attention and research, and provides strong technical support for surgical hemostasis and bonding of soft and hard tissues. In recent years, the field of bioadhesives has developed rapidly, gradually opening up the situation of various types of products with unique functions. In the medical field, bioadhesives have received more and more attention in the field of bonding and hemostasis of soft and hard parts. [0003] Photopolymerization technology is a polymerization chemical reaction c...
