“…[ 27 ] The addition of GNP yielded to the existence of a new peak, confirming the presence of GNP in nanocomposites. XRD patterns of all PVC/GNP nanocomposites showed diffraction peaks at 2 θ = 26.7° (from GNP) [ 1 ] which is associated with graphitic (002) plane [ 28 ] and 2 θ = 29.2° (Figure 3). In all of the PVC/GNP nanocomposite cases, sharp peaks for GNP were observed, and the diffraction intensity of the GNP peaks became stronger as the amount of GNP increased in proportion to PVC, which is consistent with that of polymer composites with GNP reported in the literature.…”

“…The current research studies in the nanocomposite materials focus on the improvement of the physical, mechanical, thermal, and electrical properties of them. [ 1 ] One of the most precious products of the chemical industry and the common thermoplastic material worldwide is polyvinyl chloride (PVC). The major reason for preference of PVC is that it is lightweight and naturally resistant to chemical attacks due to its high stiffness and high resistance to most acids and many other chemicals.…”

This article describes micro‐ and nanostructural, mechanical, and thermal properties of nanocomposites based on polyvinyl chloride (PVC) and graphene nanoplatelets (GNP). The primary objective of this study was to extend restricted application area of PVC due to its low thermal stability and limited mechanical properties. GNP‐filled PVC nanocomposites were prepared (0, 0.1, 0.3, 0.5, and 1.0 wt%) by colloidal blending method and characterized in detail. The highest value of the tensile strength 13.73 MPa (an increase of 58%) and the highest value of microhardness 83.42 MPa (an increase of 82%) were obtained with GNP loading content of 0.5 wt% compared neat PVC. The mechanical properties started to decrease at loading higher than 0.5 wt%; however, the thermal properties continued to increase. The differential scanning calorimetry and Fourier transform infrared analysis results of this nanocomposite confirmed that the increase in glass transition temperature from 34.99°C to 44.36°C and the decrease in the height of functional groups peaks proved to prevented segmental relaxation and intermolecular vibrations of PVC, respectively. Thermogravimetric analysis results were showed that the percentage of carbonaceous residue increased to 15.77% by increasing the GNP content from 0.1 to 0.5 wt%. As a result, the best GNP loading was at 0.5 wt% for PVC/GNP nanocomposites where mechanical and thermal properties of PVC/GNP were both enhanced.

“…Graphene have been widely used as a reinforcing component in polymeric, ceramic and metallic matrices, and enhances the properties of the composite such as electrical, thermal properties and tribological treatment. However, graphene reinforced titanium studies on mechanical properties are very restricted in literature [6][7][8][9][10]. If we give a few studies from the literature, Cao et al studied that M the graphene nanoflake (GNF) which was added to bulk Ti matrix.…”

Titanium has extraordinary features of any metallic element such as corrosion resistance, strength to density ratio etc. Due to its good features titanium can be used in the composite as a matrix material. Titanium matrix composites (TiMCs) can be used in various industries such as automotive, airplanes and especially biomaterials. Today, as carbon reinforcing material carbon nanotube (CNT), graphite and graphene are used as reinforcing materials. The graphene has the most remarkable properties in this reinforced material due to its extraordinary mechanical features, low friction and high abrasion resistance. Composite materials produced by using titanium and graphene may have remarkable mechanical and microstructural properties. This is conspicuous subject in recent years. In the present study, graphene (Gr) reinforced titanium composites were produced by powder metallurgy method. The effect of various percentages of graphene (0-0,15-0,30-0,45-0,60 wt.%) on the microstructure, density, hardness and compressive strength of Ti composites have been investigated. From the mechanical tests after sintering at 1100 o C for 120min. The highest hardness and the greatest compressive strength were obtained for 0,30 wt.% Gr reinforced composites (520.2 HV and 1137 MPa) when compared to pure titanium (419.8 HV and 780 MPa). The crystal phase and microstructure of the composites were detected by scanning electron microscopy (SEM) and X-ray diffractometer (XRD). Better mechanical properties were observed for Ti-Gr composite materials when compared pure Ti. These kinds of composites promise the future for using especially the field of biomaterials.

Teknolojinin hızla gelişmesi ile birlikte, imalat, havacılık ve otomotiv sektörlerinde yaygın olarak kullanılan standart malzemeler yerini yeni nesil yüksek mukavemete ve hafifliğe sahip malzemelere bırakmaktadır. Özellikle, Tungsten karbür (WC) ve Grafenin sahip olduğu yüksek termal ve elektriksel özellikler, yüksek elastisite modülü, yüksek mukavemet gibi üstün özellikleri sayesinde alüminyum matrisli kompozit malzeme üretiminde büyük etki ve avantajlara sahiptir. Bu çalışmada, WC ve Grafen takviyelerinin alüminyum matrisli kompozit malzemelerin mekanik özelliklerine etkisi ile ilgili çalışmalar incelenerek sunulmuştur. Alüminyum matrisli kompozitlerin mekanik özelliklerinin iyileştirilmesinde %20'ye kadar WC ve %0.7'ye kadar grafen katkısının etkili olduğu raporlanmıştır. Grafen ilavesinin %0.5'ten fazla arttırılması topaklanmalara, WC ilavesinin %30'dan fazla arttırılması ise gözenekliğin artmasına ve mekanik özelliklerin azalmasına neden olmaktadır.
