Plasma surface treatment of ceramic particles has emerged as a promising approach for developing biocomposites intended use in tissue engineering applications. Introducing functional groups on particle surfaces promotes changes material properties, enhancing adhesion, biocompatibility, and reactivity. It can also mitigate degradation during the processing polymer matrices composite materials. Therefore, carefully choosing functionalizing agent responsible generating selecting appropriate...
Abstract Zinc oxide (ZnO) was surface treated using argon plasma at 5 and 15 min, maleic anhydride (MA) in solid state as the functionalizing agent. The samples were characterized by X‐ray photoelectron spectroscopy, Fourier‐transform infrared thermogravimetric analysis. results indicate that ZnO modification occurs through two main routes: decomposition of MA plasma‐induced formation C–Zn bonds, with min being most favorable time span. Poly(lactic acid) (PLA) processed an internal chamber...
Abstract The increase in bone fractures has been driving the development of materials for repair with better mechanical and biological properties. This work reports poly (lactic acid) (PLA)‐zinc oxide (ZnO) biocomposites 3D printing scaffolds to be applied tissue engineering. ZnO surface was functionalized maleic anhydride (ZnOMA) by applying radio frequency plasma treatment as an alternative control catalytic effects on degradation PLA during molten state processing. ZnOMA powders were...
Poly (lactic acid) / zinc oxide (PLA/ZnO) composites are a promising material for scaffolds used in bone regeneration. However, ZnO particles severely degrade the polymer matrix. To prevent degradation of PLA by ZnO, it can have its surface modified. This work proposes treatment plasma, using maleic anhydride (MA) as functionalizing agent. Samples were treated argon Radio Frequency Capacitive Plasma at different times and characterized through XPS (X-Ray Photoelectron Spectroscopy), FTIR...
