Abstract:
The polymer material of silicone rubber has good properties, such as heat resistance, aging resistance, high transparency, avirulence, odorless, excellent mechanical property and biocompatibility. These kinds of materials are widely used in biological and medical fields. However, with the improvement of health standards, the demands for medical products continue to increase. Implanted into organisms, silicone rubber is likely to get infected by germs, which limits the clinical application of the materials. Some biological researchers show that, added antibacterial agent by surface modification and ontology modification, the antimicrobial properties of silicone rubber increase obviously. The addition of the antibacterial agents can inhibit microbial growth and prevent secondary infection. Controlling the types and contents of the antibacterial agents, the molding liquid silicone rubber or solid silicone rubber can keep original vulcanization, physical and mechanical properties. In this paper, preparation technology, antibacterial properties and application of antibacterial silicon rubbers are summarized. A new research idea is also discussed.
