Kuldeep Singh,Anil Ohlan,Viet Hung Pham,R. Balasubramaniyan,Swati Varshney,Jinhee Jang,Seung Hyun Hur,Won Mook Choi,Mukesh Kumar,Sundeep Kumar Dhawan,Byung-Seon Kong,Jin Suk Chung +11 more
TL;DR: Spectroscopic analysis demonstrates that the presence of GF hybrid structures facilitates strong polarization due to the formation of a solid-state charge-transfer complex between graphene and polyaniline, which leads to the high microwave absorption properties.
Journal ArticleDOI

Hyeon-Jin Shin,Won Mook Choi,Dukhyun Choi,Gang Hee Han,Seon-Mi Yoon,Hyun-Kyu Park,Sang-Woo Kim,Yong Wan Jin,Sang Yoon Lee,Jong Min Kim,Jae-Young Choi,Young Hee Lee +11 more
TL;DR: In this article, chemical dopants that modulate the electronic properties of few-layer graphene films synthesized by chemical vapor deposition were systematically modulated by the reduction potential values of dopants.
Control of Electronic Structure of Graphene by Various Dopants and Their Effects on a Nanogenerator
Hyeon-Jin Shin,Won Mook Choi,Dukhyun Choi,Gang Hee Han,Seon-Mi Yoon,Hyunkyu Park,Sang-Woo Kim,Jae-Young Choi,Young Hee Lee +8 more
TL;DR: It is demonstrated that the power generation of a nanogenerator was strongly influenced by the choice of a graphene electrode with a modified work function and leakage current was observed in graphene films with low work functions.
Journal ArticleDOI
Synthesis of a highly conductive and large surface area graphene oxide hydrogel and its use in a supercapacitor
Van Hoang Luan,Huynh Ngoc Tien,Le T. Hoa,Nguyen Thi Minh Hien,Eun-Suok Oh,Jin Suk Chung,Eui Jung Kim,Won Mook Choi,Byung-Seon Kong,Seung Hyun Hur +9 more
TL;DR: In this article, the structure of a robust and highly conductive 3D graphene oxide hydrogel is described, which is fabricated by a crosslinking reaction with ethylene diamine followed by a hydrazine reduction.
Journal ArticleDOI
Synthesis of B-doped graphene quantum dots as a metal-free electrocatalyst for the oxygen reduction reaction
TL;DR: In this article, the effect of different types of B-C bond species on the ORR catalytic activity has been investigated to clarify the origin of the electrochemical reduction of O2.
