An Aqueous Process for Preparing Flexible Transparent Electrodes Using Non-Oxidized Graphene/Single-Walled Carbon Nanotube Hybrid Solution

Autor: Min Jae Oh, Gi-Cheol Son, Minkook Kim, Junyoung Jeon, Yong Hyun Kim, Myungwoo Son

Publikováno v: Nanomaterials, Vol 13, Iss 15, p 2249 (2023)

In this study, we prepared flexible and transparent hybrid electrodes based on an aqueous solution of non-oxidized graphene and single-walled carbon nanotubes. We used a simple halogen intercalation method to obtain high-quality graphene flakes witho

Fabrication of Eco-Friendly Graphene Nanoplatelet Electrode for Electropolishing and Its Properties

Autor: Junyoung Jeong, Wanjun Yoon, Bongjin Chung, Giyoung Jeon, Seongwoo Ryu

Publikováno v: Applied Sciences, Vol 11, Iss 7, p 3224 (2021)

Electropolishing is one of the most widely applied metal polishing techniques for passivating and deburring metal parts. Copper is often used as cathode electrode for electropolishing due to its low electrical resistance and low flow values. However,

Size-Dependent Liquid Crystal Behavior of Graphene Oxides for Preparation of Highly Ordered Graphene-Based Films

Autor: Bongjin Chung, Sunghwan Jin, Junyoung Jeong, Giyoung Jeon, Seongwoo Ryu

Publikováno v: Applied Sciences, Vol 10, Iss 16, p 5570 (2020)

We report the preparation of a highly-oriented graphene-based film prepared from liquid crystal dispersion of graphene oxides (GOs). We observed that the liquid crystal behavior of GOs is highly affected by the lateral size of GO flakes: the critical
