Noncovalent functionalization of graphene with end-functional polymers
TL;DR: In this article, a stable dispersion of reduced graphene in various organic solvents was achieved via noncovalent functionalization with amine-terminated polymers, which was obtained by chemical reduction of graphene oxide in aqueous media and was vacuum filtered to generate reduced graphene sheets.
Graphene oxide liquid crystals.
TL;DR: The liquid crystallinity of graphene oxide offers a versatile route to control the molecular organization and the corresponding properties of the carbon-based materials.

Sung Jin An,Yanwu Zhu,Sun Hwa Lee,Meryl D. Stoller,T. Emilsson,Sungjin Park,Aruna Velamakanni,Jinho An,Rodney S. Ruoff +8 more
TL;DR: In this article, the deposition of films composed of overlapped and stacked platelets of graphene oxide (G-O) reduced by an electrophoretic deposition (EPD) process was reported.
Workfunction-Tunable, N-Doped Reduced Graphene Transparent Electrodes for High-Performance Polymer Light-Emitting Diodes
Jin Ok Hwang,Ji Sun Park,Dong Sung Choi,Ju Young Kim,Sun Hwa Lee,Kyung Eun Lee,Yong-Hyun Kim,Myoung Hoon Song,Seunghyup Yoo,Sang Ouk Kim +9 more
TL;DR: Workfunction-tunable, highly conductive, N-doped reduced graphene film is demonstrated, which is obtainable from the spin-casting of graphene oxide dispersion and can be successfully employed as a transparent cathode for high-performance polymer light-emitting diodes (PLEDs) as an alternative to fluorine- doped tin oxide (FTO).

TL;DR: In this paper, a mussel-inspired dopamine successfully addresses those weaknesses by improving interflake interaction and ordering in MXene assembled films, yielding an ultrathin adhesive layer, and angstrom thick polydopamine further promotes the innate high electrical conductivity and excellent EMI shielding properties of MXene films.
