硅烷化银涂层钛植入物的抗菌改性研究
Study on antibacterial modification of silanized silver coated titanium implants
摘要
Abstract
The surface modification of titanium implants needs to meet the requirements of antibacterial and biocom-patibility in order to ensure the success of implantation.The morphological characteristics,antibacterial properties,and biocompatibility of titanium surfaces were studied using different surface modification methods.The results showed that after acid etching and alkali thermal modification,uniformly distributed three-dimensional network struc-ture was formed on the surface of titanium sheets,which improved their hydrophilicity and roughness,enhanced their biological activity,and promoted cell adhesion;Silver nanoparticles were successfully prepared by chemical reaction of silver nitrate and trisodium citrate.The titanium sheets treated with silane were immersed in a synthesized nano silver solution,and silver loaded antibacterial coating was successfully constructed on the surface of the titanium sheets.At the same time,titanium sheets subjected to acid etching,alkali heat treatment,and silanization modification for 2 hours showed the highest antibacterial and biocompatibility of silver coated titanium substrates.The research results can provide reference for the production of medical titanium implants.关键词
