Highly tough cellulose/graphene composite hydrogels prepared from ionic liquids

Graphite Exfoliation to Commercialize Graphene Technology

“…FTIR spectrum of (a) CG-6 & CG-0 and (b) α-cellulose & BmimCl which provides shielding for stacking interaction between graphene sheets. This van der Waals interaction leads to graphene dispersion (Xu et al 2015).…”

“…It has exceptional electronic properties such as very conductivity (Castro Neto et al 2009), high specific area (Xu et al 2015), great thermal and mechanical properties (Changgu et al 2008;Hossain et al 2014). Graphene also widely used in fuel cells (Mahmood et al 2014), as corrosion prevention , ultraviolet photo-detector , chemical and biological sensor (Zhao et al 2016) and main component of cathode in lithium ion batteries (Patel et al 2014).…”

“…Cellulose is not melt able, insoluble in water or common solvents making it difficult to be derived or utilize. Cellulose hydrogel or cellulose composite was discovered and applied in various research fields such as food (Lavoinea et al 2016), sensing (Sadasivuni et al 2016) and tissue engineering (Singh et al 2016;Xu et al 2015). Cellulose film was fabricated using ionic liquid as solvent then plasticizer was added to improve its physical properties (Pang et al 2013).…”

“…Xu et al (2015) prepared cellulose/graphene composite from ionic liquid (IL) solution using deionized water as coagulant. Improvement in properties of cellulose was shown by adding graphene into cellulose-ionic liquid.…”

Preparation of cellulose-based fluorescent materials using Zinc sulphide quantum dot-decorated graphene by a one-step hydrothermal method

“…In most of the related studies, fluorescent cellulosebased composites were obtained from coating, printing, or adding certain functional fluorescent materials to the cellulose materials (Pathania et al 2015;Xu et al 2015;Yang et al 2015). In this work, we presented a type of cellulose-based fluorescent material by loading ZnS quantum dot-decorated graphene directly on the surface of paper fibers with a one-step hydrothermal method.…”
