“…[1][2][3][4][5] Graphene nanoplatelets (GNPs) are regarded as short stacks of less than 10 graphene layers, and may be purchased at a relatively low cost. 2,[6][7][8] GNPs are widely used as nanoadditives for advanced composites, 1,9-11 electrodes in advanced batteries 12 and ultra/super capacitors, 13,14 and the conductive component in specialty coatings 15 or adhesives. 16 GNPs are also used for exceptionally strong and impermeable packaging, better lubricants, 17 and for highly sensitive strain sensors.…”

“…Polymer nanocomposites are now considered as a substitute of traditional filled polymers (microcomposites) especially polymer-layered silicate materials. This results from particularly enhanced and upgraded properties and lightweight owing to dispersion of nanoscale filler all through the polymer network [2]. In recent years, for most researchers the most enthralling material is carbon (6th element of the periodic table).…”

Owing to remarkable electrical, mechanical, thermal, catalytic, and optical properties as well as unique structure of carbon nanotubes and graphite, they have been exploited to produce high performance and multifunctional composites. The resultant composites are differentiated on the basis of their properties to meet various applications. In the framework of this review article, we have mainly focused the preparation, structure, and properties of two families of composite materials with an emphasis on difference between them. Moreover, the current challenges, future prospective and applications of CNTs and graphite-based materials in sensors, photovoltaic and energy storage devices (Li-ion battery) have been discussed.

“…Nevertheless, pristine graphene is found to agglomerate during the formation process of homogeneous composites. Therefore, it is suggested that graphene need to undergo several modifications to overcome this problem [10]. For instance, graphene oxide (GO) which can be formed via modified Hummer's method is the most favorable material to be added into the polymer matrix as it can improve the membrane performance [4].…”

Polyethersulfone (PES)/reduced graphene oxide (rGO) membrane was prepared by phase inversion method for water treatment. Graphene oxide (GO) was obtained via modified Hummer's method and reduced to rGO where NaBH 4 was chosen as a reducing agent. FTIR was used to investigate functional groups left on rGO after reduction process. The FTIR peak at 1718 cm -1 , attributed to the carbonyl (C=O) group, was absent after GO was reduced. Interlayer spacing of GO and rGO were obtained using XRD. It was found that the interlayer spacing of GO was reduced from 7.87 to 3.68 Å after reduction process due to the removal of some of the functional groups from the material. The membrane cross section showed that addition rGO increase the length of finger-like pores as compared to neat PES when it is observed under SEM. It was observed that the membrane hydrophilicity is enhanced as the contact angle of PES reduced from 69.70 o to 32.99 o when rGO 24 hours was introduced into the polymer matrix. The highest pure water flux obtained was 174.29 L/m 2 h. The membranes showed significant enhancement when rGO was used in the polymer matrix. AbstrakMembran polietersufon (PES)/grafin oksida terturun (rGO) telah dihasilkan melalui kaedah fasa terbalik untuk rawatan air. Grafin oksida (GO) dihasilkan menerusi kaedah Hummer terubahsuai dan diturunkan kepada rGO menggunakan NaBH 4 sebagai ejen penurunan. FTIR digunakan untuk menyiasat kumpulan berfungsi yang hadir pada rGO selepas proses penurunan. Puncak FTIR pada 1718 cm -1 yang menunjukkan kumpulan karbonil (C=O) tidak hadir selepas GO terturun. Jarak antara lapisan GO dan rGO telah dikaji menggunakan XRD. Didapati jarak antara lapisan GO berkurang daripada 7.87 Å ke 3.68 Å selepas proses penurunan kerana sebilangan kumpulan berfungsi telah terkeluar dari bahan. Keratan rentas membran menunjukkan bahawa penambahan rGO meningkatkan panjang liang seperti jejari berbanding PES asli apabila dilihat menggunakan SEM. Didapati bahawa sifat hidrofilik membran telah dipertingkatkan kerana sudut sentuh air PES telah berkurang dari 69.70 o kepada 32.99 o apabila rGO 24 jam ditambah ke dalam matriks polimer. Bacaan fluks air tulen tertinggi ialah 174.29 L/m 2 h. Membran menunjukkan perubahan ketara apabila rGO digunakan di dalam matriks polimer.
