“…Therefore, several physical and chemical methods have also been reported in introducing structural defects in pristine MWCNTs. In physical methods, defects are generated in an MWCNT by ball-milling, ion,γ-ray,and 60 Co irradiation, plasma, etc . Alternatively, chemical methods of defect generation in MWCNT have also been reported, such as surface functionalization, acid treatment, hydroxylation, oxidation, etc.…”

“…The growing interest of researchers to study the gamma ray interaction with CNT has been continued. The impingement of high energy photons causes defects on CNTs surface, which was confirmed by Raman spectroscopy with 105% decreased I G /I D ratio than that of un‐irradiated CNT (I G /I D :2.12) 209 . The TEM micrographs evidenced the gradual decreasing in outer mean diameter of CNTs with increasing the dose level of gamma rays 210 .…”

Improving the wear resistance of ultra‐high molecular weight polyethylene (UHMWPE), the gold standard polymer for acetabular component in hip joint arthroplasty, is the most important challenge in joint arthroplasty. The possible ways that have been approached to this challenge are by: (i) engineering multi‐phase that is, both carbonaceous and noncarbonaceous fillers‐based polyethylene composites, which unite the inherent attributes of each element available in the system. The wear rate of carbonaceous composite is nearly 50% lower (5.11–6.69 × 10−5 mm3/Nm) than that of noncarbonaceous composite (10–12.5 × 10−5 mm3/Nm), thus, recognized as a potential reinforcement, and (ii) coupling gamma‐irradiation, which is a mandated sterilization process, with multi‐phase nanocomposite to understand the free radical‐scavenging effect of fillers and improved interfacial adhesion strength between fillers and matrix. After the exposure of gamma‐rays (50–100 kGy), the free radicals formed by bond breakage in both the reinforcements and the matrix recombine to form covalent/Van der Waals bond in the interface. Thus, dramatical improvement in wear resistance of both types of composites with 2–4 times decreased wear rate is observed compared to that of composites under un‐irradiated condition. However, enhancing the interfacial adhesion between two different phases is a major constraint in the design of UHMWPE composites. Many methods such as functionalization of reinforcements, and irradiation on functionalized UHMWPE composites that can be approached to address this constraint are documented in this review.

“…The SAED pattern in Fig. 1c shows the clear rings of the graphitic planes (002) and (100) which depicts the crystalline nature of the nanotubes without any alterations of the planes [37]. Besides, a highly crystalline nanotubes is associated with similar chirality and sharp coaxial rings with fewer halo ring pattern [8].…”

In this study, the role of multiwall carbon nanotubes (MWCNT) on the microstructural evolution and mechanical properties of Ti6Al4V-based composites was investigated. This was conducted by dispersing different concentrations (0.5, 1.0 and 1.5 wt%) of MWCNT into the Ti6Al4V matrix using shift-speed ball milling technique. Thereafter, the Ti6Al4V and the nanocomposites were consolidated via the spark plasma sintering technique. Various characterization techniques; scanning electron microscopy (SEM), transmission electron microscopy (TEM) and light microscopy were conducted to understand the microstructural evolution of the samples after the dispersion and sintering process. Subsequently, micromechanical and nanoindentation was carried out to reveal the mechanical properties of the fabricated samples. The morphological examination using SEM and TEM revealed the dispersibility of MWCNT dispersed within the Ti6Al4V matrix. Besides, the selected area diffraction and the fast Fourier Transform pattern demonstrated that the increase in concentration of the MWCNT exposed the nanotubes to adverse stresses during the dispersion process. Furthermore, the incorporation and increase in concentration of the MWCNT in the titanium alloy resulted in microstructural and phase changes, which translate to tremendous improvements in microhardness, nanohardness and elastic modulus up to 46.9%, 150.8%, and 169.5% respectively.
