Modification of acrylic bone cement with mesoporous silica nanoparticles: Effects on mechanical, fatigue and absorption properties

Influence of test specimen fabrication method and cross-section configuration on tension–tension fatigue life of PMMA bone cement

“…For the third method, the instantaneous absorbed energy (area inside the hysteresis cyclic stress-versus strain plot) and the secant modulus (slope of the cyclic stressstrain plot) for certain load cycles were each plotted against N f (Sheafi and Tanner, 2014;Slane et al, 2014).…”

Synthesis, Properties, and Humidity Resistance Enhancement of Biodegradable Cellulose-Containing Superabsorbent Polymer

“…The possible reason is that, with the monomer ratio increase, the viscosity of the reaction system increased. It weakened the probability of the active collision between monomers and shortened polyacrylic acid acrylamide graft chains, which is adverse to the formation of polymer network structure [20][21][22][23][24]. On the other hand, the amount of cellulose is important for the graft polymerization and too little amount of cellulose has an adverse influence on the graft polymerization.…”

“…Accordingly, the water absorption capacity decreased. When the ratio of oil to water is low, the water content in the monomer drops increased, the resin macromolecular chain could be fully extended, the cross-linking degree increased, and the water absorption rate decreased too [21]. Figures 8 and 9 show the effect of reaction temperature on the absorption of water and salt water.…”

Nanomaterials: The Next Step in Injectable Bone Cements

“…Generally, in polymer-based nanocomposites, stiffness primarily depends on particle loading, whereas particle-matrix interactions appear to be a critical factor for material strength [107]. Nanocomposites have been shown to display dose-dependent increases in tensile and compressive strengths, elastic modulus and toughness [75,76,108,109], but nanocomposites with poor interfacial adhesion between the nanoparticle and the surrounding matrix showed decreases in strength, toughness and future science group Nanomaterials: the next step in injectable bone cements Review stiffness [85,108,110]. However, the validity of this dose dependency is diminished when the concentration of the nanoparticles is sufficiently high for agglomeration, and as a result, there is an optimal concentration of nanoparticles (which rarely exceeds 10 wt%) that gives rise to peak compressive strength and modulus values [80,83,[111][112][113].…”
