采用液相等离子体法（PLP）对石墨烯纳米片（GNP）进行改性，制备了羟基化GNP和Ag纳米粒子物理吸附的GNP。在NaCl和氢醌水溶液中使用PLP羟基化GNP。在采用AgNO 3水溶液的PLP过程中，直径约为10-100 nm的结晶Ag纳米颗粒物理吸附在GNP上，几乎没有官能化。结果表明，随着等离子体处理时间的延长，纳米银颗粒和羟基的数量增加。(C)2020日本应用物理学会
Graphene nanoplates (GNP) were modified via the plasma in liquid process (PLP) with two types of aqueous solutions for the fabrication of hydroxylated GNP and Ag-nanoparticles-physisorbed GNP. GNP were hydroxylated using the PLP in NaCl and hydroquinone aqueous solution. During the PLP employing AgNO3 aqueous solution, crystalized Ag nanoparticles with a diameter of around 10-100 nm were physisorbed on GNP with little functionalization. It was found that the amount of hydroxyl groups and Ag nanoparticles increased with the plasma treatment time. (C) 2020 The Japan Society of Applied Physics
