“…Amongst commonly ceramic material into denture-base acrylic is Al2O3 NPs because it possesses excellent abrasion resistance, impact resistance, superior hardness, low cost, and high stability and resistance to oxidation and corrosion at high temperature. Therefore, it can be used in very wide range of industries including aerospace industry, medical applications in dental, adsorbents, microelectronics, catalysts, coatings for decorative effects and in the cosmetic or automotive industry and other high technological fields [30][31][32][33][34]. Al2O3 NPs have been attracting attention and have been historically more accepted as biomaterials for dental and medical applications [35].…”

Polymethyl methacrylate (PMMA) is one of the common widely accepted biomaterials in prosthetic dentistry due to its acceptable advantages, since 1937. In the present work, PMMA reinforced with Al2O3 nanowires (Al2O3 NWs) and ZrO2 nanoparticles (ZrO2 NPs) were fabricated by a self-curing method. Mechanical and tribological tests were conducted to study the effect of nanofillers on the mechanical and tribological performance of PMMA nanocomposites. Compression and microhardness tests, as mechanical tests, were accomplished to estimate the elastic modulus and microhardness number of the present nanocomposites. Also, tribological properties of unfilled PMMA and its nanocomposites were realized by pin-on-disk tester under dry sliding conditions. Wear test was conducted at room temperature under applied loads of 10, 20, 30, 40, and 50 N at a constant sliding speed and distance of 1.256 m/s and 226 m, respectively to study wear rate and coefficient of friction (COF) of the nanocomposites. Experimental results revealed that the elastic modulus, microhardness, wear rate, and COF were enhanced with increasing nanofiller content up to 0.5 and 0.7 wt. % of Al2O3 NWs and ZrO2 NPs, respectively. Also, wear rate increased with increasing applied loads up to 50 N, while COF decreased with increasing applied loads up to 40 N. Finally, specimens� worn surfaces were examined and imaged using scanning electron microscope (SEM).

“…So, it is necessary to use some methods such as modication, functionalization and compatibilizing of CNTs to gain a uniform dispersion of nanoparticles in the polymer matrix and promote good interfacial interaction/adhesion between the polymer matrix and nanoparticles. 3,[8][9][10] The electrical conductivity of polymer/CNT nanocomposites (PCNTs) can be increased through the formation of a ller network above the ller concentration, known as the percolation threshold. [11][12][13][14] This means that signicant conductivity of PCNTs is only obtained at or above the percolation threshold.…”

“…There are many kinds fillers such as glass fiber, carbon fiber, aramid fiber were widely used and have a great effect in raising the strength of the polymeric matrices like PTFE, polyamides, PEEK or phenolic resin.These composites mostly have a diminish wear rate compared with the pristine polymers, but still, number of factors like environment and fibres type have a great impact on the extent and the relative effectiveness of each filler (Friedrich Klaus 2008). Al-kawaz et al, they reinforced PMMA coating layer with MWCNTgrafted-PMMA and they showed that the coefficient of friction decreased with increasing the thickness of the PMMA layer on MWCNT walls or with an increasing weight fraction of polymer that grafted with the MWCNT surface (A Al-kawaz et al 2016). Li-Jun Cui et al, they study the effect of using multi-wall carbon nanotubes (MWCNTs)functionalized with carboxyl groups and amino groups, on the friction and wear resistance of the epoxy resin utilizing M-2000 wear testing machine at a variety of sliding speeds and applied normal loads.…”

Recently, scratch technique is widely used for characterizing the mechanical properties of awide range of surfaces. In the engineering applications and in order to determine the relativehardness of materials, coatings and paints evaluations, and appraisal a variety of materialdamage countenance when subjected to asperity of the hard counterface, a scratch test wassuccessfully used. In the current work, we have reviewed theoretical models that have beendeveloped in the field of scratching and the scratch way that used for characterizationpolymeric surfaces. In order to design scratch-resistant polymers, we also discussed thevarious wear and scratch damage mechanisms for polymer and its composites. In addition,we discussed the influence of types and concentration of filler on the wear and scratchresistance. The aim of this work is to review the theoretical models that have been developedin the field of scratching and the scratch way that used for characterization polymeric surfaces.
