“…As a result, these polymers are being used in medicine and medical applications to improve regeneration, restore damaged tissues, and shorten healing time. Among the polymers utilized in medical applications are poly(3-hydroxybutyrate), polylactic acid, poly(glycolic) acid, and polycaprolactone, as well as their blends and copolymers [ 1 , 2 ].…”

In the presented work, poly(3-hydroxybutyrate)–PHB-based composite blends for bone medical applications and tissue engineering are prepared and characterized. PHB used for the work was in two cases commercial and, in one case, was extracted by the chloroform-free route. PHB was then blended with poly(lactic acid) (PLA) or polycaprolactone (PCL) and plasticized by oligomeric adipate ester (Syncroflex, SN). Tricalcium phosphate (TCP) particles were used as a bioactive filler. Prepared polymer blends were processed into the form of 3D printing filaments. The samples for all the tests performed were prepared by FDM 3D printing or compression molding. Differential scanning calorimetry was conducted to evaluate the thermal properties, followed by optimization of printing temperature by temperature tower test and determination of warping coefficient. Tensile test, three-point flexural test, and compression test were performed to study the mechanical properties of materials. Optical contact angle measurement was conducted to determine the surface properties of these blends and their influence on cell adhesion. Cytotoxicity measurement of prepared blends was conducted to find out whether the prepared materials were non-cytotoxic. The best temperatures for 3D printing were 195/190, 195/175, and 195/165 °C for PHB-soap/PLA-SN, PHB/PCL-SN, and PHB/PCL-SN-TCP, respectively. Their mechanical properties (strengths ~40 MPa, moduli ~2.5 GPa) were comparable with human trabecular bone. The calculated surface energies of all blends were ~40 mN/m. Unfortunately, only two out of three materials were proven to be non-cytotoxic (both PHB/PCL blends).

“…This forming method can make near-net shapes and complex products through rapid and low-cost production with a low workforce. Several materials, e.g., metal, polymer, ceramic, and composite materials, can be printed by 3Dprinting technology [8][9][10][11]. Polymer-matrix composites (PMCs) are composite materials that mix between polymer matrix and reinforcement, such as metal particles or fibers.…”

Iron oxide scale generally forms on low-carbon steel surfaces during the hot rolling processes andproduces as solid waste more than 100 thousand tons per year. The utilization of the iron oxide scaleis one possible way to reduce the production cost for steel plants and promote environmental protection. Acrylonitrile-Butadiene-Styrol-Copolymer (ABS) is widely used as engineering plastic for automotive parts because of its high strength and wear resistance. The recycling of iron oxide waste as reinforcement particles for enhancing the tensile strength of ABS composite was studied. The iron oxides were recycled by carbon powder at a high temperature between 1150℃ to 1350℃ up to 120 min. After the reduction process, the reduced iron from an optimal condition with the iron-rich fraction was ground to powder. Afterward, the 0.3 vol% to 1.3 vol% powders were mixed with ABS polymer powder and formed as composite filaments for additive manufacturing (FDM 3D printing). The tensile strength of pure ABS filament increased to 37.16 ± 2.37 MPa when added recycled iron powders. The regular distribution and 13.68 ± 9.78 µm of recycled-iron particle sizes on the ABS matrix were investigated and correlated to the mechanical properties.

“…Fermentation of starch from various plants, such as cassava, maize, and sugarcane has been generally used to produce the LA monomer required for the preparation polylactic acid. High‐molecular weight of polylactic acid could be obtained through a variety of industrial processes (Abdelrahman, Nassar, Mashaly, Mahmoud, Maamoun, El‐Sakhawy, et al, 2020; Aljohani et al, 2021; Liu et al, 2020; Müller et al, 2022; Surisaeng et al, 2022; Zhao et al, 2021). Appliances and disposable dinnerware, and gadgets like mobile devices and laptops are all examples of consumer items prepared from polylactic acid.…”

The outstanding biodegradability, biocompatibility, affordability, and renewability of polylactic acid have made it a prominent biomaterial. Herein, an innovative, easy, and eco-friendly technique is used to prepare sodium polylactate (SP)-based nanofibers.Solution blowing spinning (SBS) was used to create fibrous mats of SP and polyvinyl alcohol (PVA). SBS's SP nanfibers were crosslinked using an aqueous solution of calcium chloride to produce moisture-resistant calcium polylactate nanofibrous spun mats.Both of UV-visible absorption spectra and transmission electron microscopy were utilized to study the produced zinc oxide (ZnO) nanoparticles (NPs) to indicate a diameter of around 15-23 nm with a high intensity absorption intensity at 370 nm. New polylactate copolymer was synthesized and characterized by infrared and NMR spectroscopic techniques. In order to prepare SP/PVA/ZnO nanocomposite nanofibers, various ZnO ratios were used. The morphologies of the composite nanofibers were investigated by infrared spectroscopy (FTIR), energy-dispersive X-ray analyzer, and
