“…In contrast with our previous data the characteristic feature of HA as a filler for UHMWPE is its chemical and surface activity that gives rise to chemical bonding with the polymer [12]. HA microfiller demonstrates these properties to a less extent (Figure 8).…”

The influence of modification by hydroxyapatite (HA) nano- and microparticles on tribotechnical properties of ultrahigh-molecular-weight polyethylene (UHMWPE) was investigated to develop polymer implants for endoprosthesis. It was shown that modification of UHMWPE by hydroxyapatite nanoparticles within range of 0.1–0.5 wt.% results in increase of wear resistance at dry sliding by 3 times. On the other hand adding of 20 wt.% of micron size HA gives rise to the same effect. The effect of increasing wear resistance is not substantially changed at surface treatment of the nano- and microcomposites by N+ion beams as compared with nonirradiated blends. Preliminary joint mechanical activation of UHMWPE powder and fillers results in more uniform distribution of nanofillers in the matrix and, as a result, formation of more ordered structure. Structure within bulk material and surface layers was studied by means of optical profilometry, scanning electron microscopy, infrared spectroscopy, and differential scanning calorimetry. It is shown that adding of hydroxyapatite nanoparticles and high-energy surface treatment of the composite by N+ion implantation improve tribotechnical properties of UHMWPE due to formation of chemical bonds in the composite (crosslinking) and ordering of permolecular structure.

“…In the course of investigations by DSC revealed phase transitions in self-reinforcing materials based on UHMWPE containing nanoparticles of transition metal oxides, not peculiar to the starting UHMWPE. Thus is confirmed the previously expressed position on the impact of nano-sized additives on the supramolecular structure of UHMWPE, reflected in the increase in the degree of crystallinity, which has a beneficial effect on the properties of materials, as most of the ordering of packaging macromolecules polymer promotes the values of the strength, abrasion resistance 6 . Of particular note is the growth temperature of the onset of melting materials based on UHMWPE containing nanoparticles of oxides of zirconium and hafnium, and a more pronounced influence of hafnium oxide nanoparticles that can be attributed to a greater polarization of the surface of these particles.…”

“…The X‐ray protective, mechanical, and chemical properties were improved when ultra‐high molecular weight polyethylene (UHMWPE) was filled with tungsten and B 4 C particles . Various studies were carried out on UHMWPE with variety of fillers like aluminum oxide (Аl 2 О 3 ), copper (Cu) and silicon dioxide (SiO 2 ), graphite, and molybdenum disulfide (MoS 2 ), to enhance different properties of the respective UHMWPE hybrid polymer composites. The synergetic properties of two or more fillers in a polymer matrix led to development of hybrid composites with an overall improvement in mechanical, thermal, chemical, and physical stability …”

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.
