Mg-Based Metallic Glass-Polymer Composites: Investigation of Structure, Thermal Properties, and Biocompatibility

Abstract

<jats:p>In this work, the biomedical applicability and physical properties of magnesium-based metallic glass/polycaprolactone (PCL) composites are explored. The composites were fabricated via mechanical alloying and subsequent coextrusion. The coextrusion process was carried out at a temperature near to the supercooled liquid region of the metallic glass and the viscous region of the polymer. The structures, as well as thermal and mechanical properties of the obtained samples were characterized, and in vivo investigations were undertaken. The composite samples possess acceptable thermal and mechanical properties. Tensile tests indicate the ability of the composites to withstand more than 100% deformation. In vivo studies reveal that the composites are biologically compatible and could be promising for biomedical applications.</jats:p>

Potential bioactive coating system for high-performance absorbable magnesium bone implants

“…It should also enhance mechanical properties and bioactivity and decrease the corrosion rate. Many reinforcing particles were used, such as HA, β-tricalcium phosphate (β-TCP), bioactive glass, Ca-polyphosphate, fluorapatite, bredigite, Zn oxide, Mg oxide, Ti dioxide, graphene oxide, carbon, and polymers [ [48] , [49] , [50] , [51] ]. In metal matrix composites, care should be taken to improve the interfacial bonding to avoid detachment of the reinforcement from the Mg matrix during the degradation.…”

Role of Mixing and Milling in Mechanochemical Synthesis (Review)

“…Mechanochemical synthesis can provide a wide variety of inorganic compounds: metals, intermetallic compounds [1,3,9,15,17,22,[35][36][37][38][39][40][41][42], simple and complex oxides [1-6, 9, 18, 20, 21, 43-45], chalcogenides [1-3, 5, 23-25, 46-49], salts [1,3,20,50], micro-and nanoporous structures [7,[10][11][12][13][14][51][52][53][54], hybrid and composite materials with unusual properties [55], nanoparticles [5,6,9,17,[23][24][25][56][57][58][59], catalysts [60][61][62][63][64], calcium phosphate ceramic materials, spinel-based overstoichiometric lithium intercalation compounds [65]…”

Investigation of Thermophysical Properties of Zr-Based Metallic Glass-Polymer Composite

“…The criteria for choosing the polymer were its physical properties and its melting temperature near the supercooled region of the metallic glass. This criterion was also used in our previous works [41][42][43]. The composites have a melting temperature of 346 • C for 30/70, 347 • C for 50/50 and 348 • C for 70/30 (Figure 2b) composites.…”

“…Additionally, the composite showed good thermal properties as compared to Mg 67.5 Ca 5 Zn 27.5 and Cu 54 Pd 28 P 18 metallic glasses. In another study, Mg 66 Zn 30 Ca 4 /Polycaprolactone (PCL) [43] composite was produced by ball milling and subsequent co-extrusion. The co-extrusion temperature was near the supercooled temperature of the metallic glass.…”
