The unique properties of Graphene-based nanocomposites have attracted numerous investigations in the field of materials science from supercapacitors to drug delivery applications. Graphene has received attention as a probe or electrode material source for supercapacitors because it consists of low electrical resistance, large electrolyte accessibility based on the larger surface area and chemical stability. The extra properties of graphene show some promising application such as optical electronics, composites and others. Supercapacitors are able to store more energy and can be fully charged / discharged at high speeds. This review has been mainly focused on the following points namely synthesis route of Graphene which consists of Bottom-Up and Top-Down approaches, are more difficult and hindering the massive production of graphene. We have also discussed the different techniques utilized for the synthesis of reduced graphene oxide namely thermally, hydrothermally, partially and electrochemically reduced graphene oxide and its electrochemical behavior. Analysis of these results inferred the specific capacitance in the range of 220,223.6, 225 and 230 F/g (acid and neutral). The characterization of Graphene/Nanocomposites by RAMAN, FTIR, SEM and TEM analysis were also reviewed and found to be suitable for supercapacitors. In this review, the current development of the synthesis route of graphene oxide and its composites with future prospects is presented and discussed.

“…Calcium carbonate, CaCO 3 , is an important industrial pigment and filler material in numerous applications, such as plastic-based composites, paints, food, ceramics and the paper industry. Recently, composite materials consisting of CaCO 3 , microfibers and nanocellulose have gained interest in the search for new ways of improving the water removal from hardto-dewater fiber-based furnishes (Rantanen et al 2015;Dimic-Misic et al 2017), substrates for printed electronics (Penttilä et al 2012;Torvinen et al 2012Torvinen et al , 2015 and transparent films (Gebauer et al 2011). Additionally, a fairly recently developed cogrinding method of microcellulose (MFC) production is claimed to be industrially scalable, and results in a mixture of MFC and mineral such as CaCO 3 (Svending 2014).…”

Effect of PCC crystallization and morphology on flocculation with microfibrillated cellulose, on sheet densification and liquid absorption behavior

Composite sheets consisting of elongated and aggregated cationically charged precipitated calcium carbonate (PCC) and native microfibrillated cellulose (MFC) were prepared with a wet laying method. The furnishes were prepared with and without an anionic flocculating agent (polyacrylamide) in order to adjust the structure of the sheet. The samples were compressed (densified) in order to determine the particle and microfibrillated cellulose-PCC structure coalescence and densification, as well as its subsequent influence on liquid absorption behavior. The densification affected both the vertical and lateral distribution of PCC, but the flocculating agent enhanced the compression stability and stabilized the sheets against PCC material flow. The differences between the sheets made with and without the flocculation aid affected the absorption of an anionic dye-based fluid ink, which was evident as a higher print density and less print bleeding. The absorption behavior was dependent on the sheet structure, especially on the PCC distribution within the sheets. Finally, the role of MFC on floc structure and floc formation is discussed.

“…The research activities on sustainable and environmentally sound raw materials especially in printed electronics have increased globally due to remarkable population growth together with limited biophysical resources. The CNF films are potentially utilized in certain printed electronics applications [16][17][18][19]. The requirements for surface smoothness and dimensional stability at high humidity, however, are demanding in most of these applications so that the traditional CNF films cannot fulfil them sufficiently.…”
