Processing Technology and Characteristic Evaluation of Polylactic Acid/316L Stainless Steel Composite Braids with Hydroxylapatite Deposition
Biodegradable polymer has been widely used in surgical suture, dressing, artificial bone and other bone-related applications. Studies have demonstrated that metals, such as titanium, titanium alloys or 316L stainless steel, can be widely used in dental and maxillofacial surgeries. The present study aimed to fabricate a scaffold with a blend of multilayer polylactic acid (PLA) ply yarns with 316L stainless steel (SS) braids, which was then immersed in simulated body fluid (SBF), forming the PLA/SS composite braid with hydroxylapatite deposition. After being immersed in SBF for 14 days, the PLA/SS composite braid was covered with precipitate which was confirmed to be apatite deposition according to surface observation and EDS evaluation.
