Carbon Nanotubes in Nanocomposites and Hybrids with Hydroxyapatite for Bone Replacements
Hydroxyapatite (HA), as a bone mineral component, has been an attractive bioceramic for the reconstruction of hard tissues. However, its poor mechanical properties, including low fracture toughness and tensile strength, have been a significant challenge to the application of HA for the replacement of load-bearing and/or large bone defects. Among materials studied to reinforce HA, carbon nanotub...
متن کاملBacterial Cellulose-Hydroxyapatite Nanocomposites for Bone Regeneration
The aim of this study was to develop and to evaluate the biological properties of bacterial cellulose-hydroxyapatite (BC-HA) nanocomposite membranes for bone regeneration. Nanocomposites were prepared from bacterial cellulose membranes sequentially incubated in solutions of CaCl(2) followed by Na(2)HPO(4). BC-HA membranes were evaluated in noncritical bone defects in rat tibiae at 1, 4, and 16 ...
متن کاملEffective Mechanical Properties of Nanocomposites Reinforced With Carbon Nanotubes Bundle
Nanocomposites made of Carbon Nanotube (CNT) bundles have attracted researchers’ attention due to their unusual properties such as: light weight, flexibility and stiffness. In this paper, the effects of straight and rope-shaped bundles on nanocomposite effective mechanical properties are investigated. First, FEA models are created consisting of CNTs with different shapes of straight and rope-...
متن کاملCarbon nanotubes in novel ceramic matrix nanocomposites
Novel carbon nanotubes±metal±ceramic nanocomposite powders and dense materials have been prepared and their microstructure and mechanical properties have been investigated. After a brief review on the structure, synthesis and physical properties of carbon nanotubes, we describe an original catalytic method that produces ceramic±matrix composite powders that contain in situ grown nanotubes. The ...
متن کاملRelease of Carbon Nanotubes from Polymer Nanocomposites
Carbon nanotube (CNT)/polymer nanocomposites have superior properties compared to the neat polymer matrix. They now are widely used in industry, but questions have been raised about the risks of such materials since CNTs can be toxic when inhaled. For a risk assessment of CNT nanocomposites, it is crucial to know whether CNTs from nanocomposites can be released into the environment or if they r...
