“…Furthermore, GO can be surface-treated to yield better interface properties and tribology performance as compared to untreated GO [ 84 , 85 , 86 ]. Amino groups [ 85 ], polyetheramine-functionalized GO [ 86 ] and remaining oxygenic groups of GO interact well with the epoxy system to resist crack propagation and fatigue wear.…”

“…Moreover, other researchers reported that possible surface modifications on HNT are vinyltrimethoxy silane (VTMS) and N,N’-ethylenebis(stearamide) (EBS). VTMS-treated HNT improved the wear resistance of the HDPE matrix [ 84 ], whereas EBS formed hydrogen bonds with HNT to improve the interfacial compatibility and lower COF [ 99 ].…”

“…Titanium nitride (TiN) nanopowder acted as an effective solid lubricant for HDPE nanocomposites during the wear process, reducing COF by about 12% [ 83 ]. In a later study, VTMS-treated TiN nanopowder was incorporated together with a trace amount of organic peroxide to result in a 48% reduction in WR [ 84 ]. 2D transition metal carbides with the molecular formula of Ti 3 C 2 T x , where T x denotes the surface functional groups, was incorporated into the epoxy matrix.…”

Polymer nanocomposites with enhanced performances are becoming a trend in the current research field, overcoming the limitations of bulk polymer and meeting the demands of market and society in tribological applications. Polytetrafluoroethylene, poly(ether ether ketone) and ultrahigh molecular weight polyethylene are the most popular polymers in recent research on tribology. Current work comprehensively reviews recent advancements of polymer nanocomposites in tribology. The influence of different types of nanofiller, such as carbon-based nanofiller, silicon-based nanofiller, metal oxide nanofiller and hybrid nanofiller, on the tribological performance of thermoplastic and thermoset nanocomposites is discussed. Since the tribological properties of polymer nanocomposites are not intrinsic but are dependent on sliding conditions, direct comparison between different types of nanofiller or the same nanofiller of different morphologies and structures is not feasible. Friction and wear rate are normalized to indicate relative improvement by different fillers. Emphasis is given to the effect of nanofiller content and surface modification of nanofillers on friction, wear resistance, wear mechanism and transfer film formation of its nanocomposites. Limitations from the previous works are addressed and future research on tribology of polymer nanocomposites is proposed.

“…Graphene indeed has been used to fabricate high performing materials with novel functionalities for electric conductive composites, ultrasensitive sensors, super-capacitor electrodes, thermally stable, and mechanically reinforced materials [ 26 , 27 , 28 , 29 , 30 ]. Successful polymerizations of poly(methyl methacrylate), epoxy and poly(arylene disulfide) with graphene oxide or silicone foams and polyurethane with thermal reduced graphene oxide have been reported [ 26 ], as well as graphene nanoplatelet composites with epoxy thermosetting resin [ 31 ], nylon 6,6 [ 32 ], poly(ethylene) [ 33 ], poly(propylene) [ 34 ], silicone [ 35 ], or poly(1,4-cis-isoprene) rubber [ 36 ]. Some recent examples reported graphene and bio-based polymers as poly(butylene succinate) [ 37 ], poly(hydroxyalkanoates) [ 38 ], poly(vinyl alcohol) [ 26 ], alginate foam and hydrogels for environmental remediation [ 39 , 40 ].…”

Bio-Based Furan-Polyesters/Graphene Nanocomposites Prepared by In Situ Polymerization

In situ intercalative polymerization has been investigated as a strategic way to obtain poly(propylene 2,5-furandicarboxylate) (PPF) and poly(hexamethylene 2,5-furandicarboxylate) (PHF) nanocomposites with different graphene types and amounts. Graphene (G) has been dispersed in surfactant stabilized water suspensions. The loading range in composites was 0.25–0.75 wt %. For the highest composition, a different type of graphene (XT500) dispersed in 1,3 propanediol, containing a 6% of oxidized graphene and without surfactant has been also tested. The results showed that the amorphous PPF is able to crystallize during heating scan in DSC and graphene seems to affect such capability: G hinders the polymer chains in reaching an ordered state, showing even more depressed cold crystallization and melting. On the contrary, such hindering effect is absent with XT500, which rather induces the opposite. Concerning the thermal stability, no improvement has been induced by graphene, even if the onset degradation temperatures remain high for all the materials. A moderate enhancement in mechanical properties is observed in PPF composite with XT500, and especially in PHF composite, where a significative increase of 10–20% in storage modulus E’ is maintained in almost all the temperature range. Such an increase is also reflected in a slightly higher heat distortion temperature. These preliminary results can be useful in order to further address the field of application of furan-based polyesters; in particular, they could be promising as packaging materials.

“…For this reason, micro and nanoscale characterization techniques have established themselves both in the field of scientific research and in the field of industrial research [ 6 ]. Some of these techniques are now accessible for accurate characterizations, even at the production stages [ 7 , 8 ]. Among the others, nano-indentation and atomic force microscopy (AFM) based techniques (HarmoniX and Peak Force) are the most interesting and promising [ 9 ].…”

Morphology-Mechanical Performance Relationship at the Micrometrical Level within Molded Polypropylene Obtained with Non-Symmetric Mold Temperature Conditioning

The control of the structural properties of a polymeric material at the micro and nano-metrical scale is strategic to obtaining parts with high performance, durability and free from sudden failures. The characteristic skin-core morphology of injection molded samples is intimately linked to the complex shear flow, pressure and temperature evolutions experienced by the polymer chains during processing. An accurate analysis of this morphology can allow for the assessment of the quality and confidence of the process. Non-symmetric mold temperature conditions are imposed to produce complex morphologies in polypropylene parts. Morphological and micromechanical characterizations of the samples are used to quantify the effects of the processing conditions on the part performance. Asymmetric distribution of temperatures determines asymmetric distribution of both morphology and mechanical properties. The inhomogeneity degree depends on the time that one side of the cavity experiences high temperatures. The spherulites, which cover the thickest of the parts obtained with high temperatures at one cavity side, show smaller values of elastic modulus than the fibrils. When the polymer molecules experience high temperatures for long periods, the solid-diffusion and the partial melting and recrystallization phenomena determine a better structuring of the molecules with a parallel increase of the elastic modulus.
