Synthesis, Processing, and Characterization of the Resorbable Composites

The chapter titled Synthesis, Processing, and Characterization of Resorbable Composites provides a comprehensive overview of the development and evaluation of resorbable materials for biomedical use. It covers various synthesis methodologies for polymers such as poly(octamethylene citrate) (POC) and poly(L-lactideco-D,L-lactide) (PLDLA), noting POC's enhanced degradation resistance due to improved crosslinking and lower hydrophilicity. The chapter explores multiple fabrication techniques, including chemical precipitation, electrospinning, and solgel methods, with emphasis on controlling factors like the Ca/P ratio and crystallinity to closely mimic natural apatite structures. It further examines advanced processing approaches such as microemulsion, microwave irradiation, and 3D printing, highlighting their roles in achieving phase purity, particle uniformity, and customized scaffold design. Characterization techniques—including mechanical testing, X-ray diffraction (XRD), scanning electron microscopy (SEM), and degradation studies in phosphate-buffered saline—are discussed in the context of predicting in vivo behavior. The chapter concludes by linking these materials and methods to practical applications like bone grafts, drug delivery systems, and bioactive implants, underlining the importance of integrating design, processing, and performance for successful clinical translation.
