“…The novel part of this study is that no work has been carried out with the combination of three radiation resistant nanofillers like B 4 C, WC, and MWCNT in PAEK. In our earlier work, the static, dynamic mechanical, wear, and the thermal decomposition properties with B 4 C and MWCNT nanofillers in PAEK polymer was reported . The present study focuses on the synergetic effect of B 4 C, WC, and MWCNT nanofillers in PAEK polymer in improving the tensile, dynamic mechanical, and thermal degradation properties.…”

This study involves the development and thermo-mechanical characterization of the individual, binary, and ternary nanocomposites using radiation resistant fillers like boron carbide (B 4 C), tungsten carbide (WC), and functionalized multi-walled carbon nanotubes (F-MWCNT) in a high performance polymer, namely, poly aryl ether ketone (PAEK). Transmission electron microscopy studies revealed the distribution and dispersion of nanofillers in the matrix. It has been observed that the presence of WC and F-MWCNT in PAEK matrix significantly enhanced the tensile strength of the composite whereas B 4 C made it stiff and brittle in nature. The tensile property improvement caused by WC and F-MWCNT has been correlated with the tensile fracture surface morphology studies. Dynamic mechanical analysis provided insight into the positive effect of nanofillers in delaying the relaxation of polymer chains. The thermogravimetric analysis gave indications on the increase in the thermal stability of the nanocomposites with the increase of nanofillers content.

“…Both pristine PEEK and 0.5GO-PEEK have a melting point around 334 ºC and exhibit a two-step decomposition. The first degradation stage can be attributed to the dehydrogenation and decomposition of polymer segments[42,43], the weight loss is about 45.35 wt% for 0.5GO-PEEK, 3% lower than that for pristine PEEK. The second degradation process is the result of the carbonization (such as benzene rings in the polymer chain), and the weight loss of 0.5GO-PEEK about 9.30 wt%, 13.3% lower than that of PEEK.…”

Biocompatible polyetheretherketone (PEEK) is a favorable material for hard tissue repair due to its similar elastic modulus to that of the human bone. In this work, graphene oxide (GO) reinforced PEEK nanocomposites with different GO loading have been prepared by injection molding. Mechanical testing reveals that the toughness of the reinforced composite varies with the GO loading, with 0.5% GO giving the greatest elongation at break (86.32% greater than pristine PEEK). The underlying toughening mechanism has been attributed to the well-dispersed GO forming π-π* conjugations at the GO / PEEK interface. These conjugations also acted as the nucleation sites for oriented crystallized region in PEEK. As the GO content increases further (e.g > 0.5%), the fillers tend to agglomerate and would disturb the crystallites of PEEK and serve as stress concentration sites, resulting in decreased toughness. The biocompatibility of the composites has been evaluated in vitro, and the results showed that the addition of GO into PEEK favors the adhesion and spreading of bone marrow stromal stem cells, demonstrating the strong potential of our GO reinforced PEEK composites in applications such as hard tissue repair and replacement.

“…The eroded particles contained matrix material in debris form. 24 It should be noted that pure PEEK has high wear and mass loss when compared to all the reinforced nanocomposites. A comparative result of the mass loss of all the samples is shown in Figure 6 and comparative result wear rate in Figure 7.…”

This study investigates the effect of dispersion of nanofiller reinforcement high performance polymer matrix to enhance the thermo-mechanical properties for bearing application. Polyetheretherketone (PEEK) matrix is reinforced with acid fucntionalized multiwalled carbon nanotubes ( f-MWCNTs) and similar matrix was then reinforced with nano tungsten carbide (nano WC) to comparatively present their mechanical, thermal and morphological properties. The Nanocomposites were prepared via melt compounding method followed by injection moulding technique. The PEEK/ f-MWCNT s nanocomposite exhibited better property enhancement than the PEEK/nano WC. Spectroscopical analysis confirmed the effectiveness of improved interfacial adhesion between PEEK and f-MWCNTs. Transmission Electron Microscope (TEM) micrograph depicted improved dispersion of f-MWCNTs in PEEK matrix than that of nano WC. Due to improved interfacial interaction between f-MWCNT s and PEEK, this resulting nanocomposite showed better mechanical, thermal and morphological properties than PEEK/nano WC. Due to ceramic nature of nano WC and higher density difference the agglomeration of particles occurred leading to lower properties.
