Structure and Property Evolution of Microinjection Molded PLA/PCL/Bioactive Glass Composite

Polymers, Journal Year: 2025, Volume and Issue: 17(7), P. 991 - 991

Published: April 6, 2025

In this study, the microinjection molding technology was adopted to prepare polylactic acid (PLA)/polycaprolactone (PCL)/bioactive glass (BG) composites with varying BG contents for biomedical applications. The various measurement techniques, including scanning electronic microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, water contact angle (WCA) test, mechanical and in vitro biological evaluations, were applied characterize above interesting biocomposites. experimental results show that extremely strong shear force field generated during process could induce situ formation of micron PCL dispersed phase fibril structures strongly promote homogeneous dispersion filler particles PLA/PCL polymer matrix, which therefore leads a significant improvement specific property PLA/PCL/BG composite. For example, fillers content increasing 10 wt%, Young's modulus obtained composite reach 2122.9 MPa, is 1.47 times higher than unfilled blend material. addition, it also found under simulated body fluid (SBF) environment, incorporated matrix be effectively transformed into hydroxyapatite (HA) components on treated sample surface, thus being greatly advantageous enhancing material's bioactivity. Obviously, molded biocomposites exhibit excellent comprehensive performance, revealing processing method hold great potential industrialization applications resulting biodegradable materials.

Mechanical and Corrosion Behaviour in Simulated Body Fluid of As-Fabricated 3D Porous L-PBF 316L Stainless Steel Structures for Biomedical Implants

Journal of Functional Biomaterials, Journal Year: 2024, Volume and Issue: 15(10), P. 313 - 313

Published: Oct. 21, 2024

Laser powder bed fusion (L-PBF) is one of the most promising additive manufacturing technologies for creating customised 316L Stainless Steel (SS) implants with biomimetic characteristics, controlled porosity, and optimal structural functional properties. However, behaviour as-fabricated 3D SS structures without any surface finishing in environments that simulate body fluids remains largely unknown. To address this knowledge gap, present study investigates internal corrosion simulated fluid (SBF), mechanical properties manufactured by L-PBF rhombitruncated cuboctahedron (RTCO) unit cells two distinct relative densities (10 35%). The microstructural analysis confirmed RTCO structure has a pure austenitic phase roughness ~20 µm fine cellular morphology. micro-CT revealed presence keyholes lack pores both structures. Despite difference remain within range bone tissue line Gibson Ashby model. Additionally, demonstrated passive SBF solution. Thus, porous are biomaterials due to their suitable roughness, properties, resistance, facilitating growth.
