Facile preparation of large-scale graphene nanoscrolls from graphene oxide sheets by cold quenching in liquid nitrogen

Graphene nanoribbon winding around carbon nanotube

“…To date a number of experimental methods for synthesis of scrolled graphene nanoribbons and the study of their structure and properties have been developed [24][25][26][27][28][29][30][31]. Structure and properties of graphene nanoscrolls (GNS), apart from experimental methods, have been extensively studied with the help of firstprinciples calculations [32][33][34], molecular dynamics [35][36][37][38][39][40][41][42][43][44][45][46] molecular mechanics [47] and using the spiral elastic rod model [35,40,48,49].…”

Controllable synthesis of graphene scrolls and their performance for supercapacitors

“…5,6 Moreover, for all of the samples the GSCs cross each other and form a 3D network, which has been characterized in our previous work. 20 More interestingly, we also noticed that with an increase in the amount of SC, the curled structure of the GSCs is obviously changed. In Fig.…”

Self-Assembly of Two-Dimensional Nanosheets into One-Dimensional Nanostructures

“…More importantly, the FGBs obtained demonstrated excellent elasticity, making this a great candidate for future flexible electronics. Recently, the cold quenching effect caused by liquid nitrogen was also utilized by Zhao et al 72 to fabricate graphene nanoscrolls using GO solution. A typical process mainly includes three steps: cold quenching in liquid nitrogen, freeze drying, and subsequent thermal reduction.…”
