Technical Field
The bioactive glass is prepared from SiO 2 -CaO-P 2 O 5 -Na 2 The inorganic material composed of O quaternary chemical components mainly has biological activity mainly because alkaline earth metal and alkali metal ions connected by non-bridging oxygen in the three-dimensional network of the biological activity glass are in aqueous medium, ca 2+ Or Na (or) + Is readily water soluble and releases to form a hydrogel layer of hydrous silicic acid, and is therefore referred to as bioactive glass. For decades, a number of studies have demonstrated that bioactive glass has good osteogenic properties, good biocompatibility and self-degrading properties. When the bioactive glass is used as a bone defect repairing material, the bioactive glass can quickly regenerate bone tissues, and the structure and mechanical properties of regenerated bone are well matched with the bone defect part; also, the research shows that the bioactive glass can promote the regeneration of soft tissues such as skin and the like, and has the function of obviously promoting the healing of skin wound surfaces. The biologically active glass was cultured with intestinal epithelial cells by a learner and found that the biologically active glass can promote proliferation of intestinal epithelial cells. However, the dispersibility of the bioactive glass particles in human bodies or organic polymers is poor, and the combination of the bioactive glass and the organic phase is loose, so that the mechanical property and the use function of the composite material are affected. In order to solve the problems, related researches such as CN201210358478.2, CN201611163396.7, CN201811478997.6 and CN201911356221.1 and the like at home and abroad have been reported to modify the surface of bioactive glass by using a silane coupling agent, improve the interfacial compatibility of the bioactive glass and an organic polymer in a chemical bonding mode, improve the bonding capability and dispersibility of the bioactive glass and the organic polymer and enhance the mechanical property of the composite material.
The silane coupling agent is an organosilicon compound having a molecular structure containing a hydrolyzable group and a functional group, and the structure is generally represented by Y n SiX (4-n) Wherein X represents a hydrolyzable group including an alkoxy group, an acyl group, a chlorine atom and the like; the molecular structure of the silane coupling agent is Y which represents a functional group, including alkenyl, epoxy, amino, mercapto, hydroxyl, isocyanate, halogenated alkyl and the like; n is selected from integers from 1 to 3; when the X groups are hydrolyzed, si-X is converted into Si-OH, hydroxyl groups in the Si-OH can be dehydrated and condensed to generate Si-O-Si bonds, and can be combined with Si-OH on the surfaces of glass, silicon dioxide, ceramics and some metal materials or in other molecules to form Si-O-Si bonds, so that functional groups such as alkenyl groups, epoxy groups, amino groups, mercapto groups, hydroxyl groups, isocyanate groups, halogen atoms and the like which can be subjected to chemical reaction can be introduced on the surfaces of the glass, the silicon dioxide, the ceramics or some metal materials. So the silane coupling agent is mainly applied to surface modification of silica materials or ceramics and the like or improves the interface compatibility of composite materials thereof. According to the characteristics of functional groups of the existing silane coupling agent, the surface characteristics of materials to be treated, the modification requirements and the application requirements of some new fields, importance is attached to the re-functionalization of the silane coupling agent. The re-functionalization of the existing silane coupling agent is mainly realized by bonding a structural unit with stronger function through the functional group, so that new functions and applications of materials to be modified are given, for example, CN201010503258.5, CN201610807720.8, CN202010940152.5, CN202110914812.7, CN201610766177.1, CN202010446615.2, CN201910559445.6, CN201811365280.0, CN201310134973.X and the like disclose silane coupling agents carrying quaternary ammonium cations, zwitterions or polyether chains, copolymers containing zwitterionic olefin monomers and olefin silane coupling agents and the like as surface modifying agents of inorganic materials such as glass or silica gel and the like, and positive effects are obtained.
In view of this, in combination with previous research results of the subject groups ZL201910993648.6, ZL2021107850204, ZL201910994314.0, ZL201811189217, CN2023100519084, CN202310116727.5, CN 202310116725.6, etc., the present inventors have made a re-functionalization design of commercially available 3-aminopropyl silane coupling agents, creating a multifunctional silane coupling agent with novel molecular structure. The hydrolyzable group in the molecular structure of the multifunctional silane coupling agent is still a traditional trialkoxy group; the amino group in the 3-aminopropyl silane coupling agent is subjected to almost quantitative aza-Michael addition reaction with diallylamino polyether acrylate, and then is subjected to quaternization reaction with an alkylating agent, propane sultone or gamma-butyrolactone, so that the multifunctional silane coupling agent has more than one quaternary ammonium cation, or sulfobetaine or carboxyl betaine in a molecular structure. Therefore, the multifunctional silane coupling agent is used for surface modification of bioactive glass, so that the enhancement effects of biocompatibility, antibacterial property and hydrophilicity of the surface modified bioactive glass can be obtained; meanwhile, the diallylammonium which is remained on the surface modified bioactive glass has the characteristic of participating in the copolymerization reaction of olefin monomers.
