品牌： Sigma

品名： 氧化石墨烯

规格： 1 G

一般描述

The material basically consists of exfoliated graphene nanoplatelets containing functional organic groups. The oxygen

content is less than 5%; the majority groups are hydroxyls (OH), which enables further chemical modifications to add

new functionalities. The functionalization approach was designed to attach most of the groups on the border of the foils,

aiming to preserve the intrinsic properties of graphene (e.g.: electric conductivity).

形态：棕色/黑色粉末

体积密度：~1.8 g/cm3

溶解性：可分散于水和极性溶剂中

层数：15-20

氧化: 4-10%

应用

The product is aimed for dispersion and/or incorporation in polar solvents (e.g.: water, THF and DMF) and polar polymeric

matrices (e.g.: PLA, PA and PET). It is suitable for in situ polymerization, direct resin mixing and molding, solvent dissolution,

extrusion processing after incorporation. Potential applications include:

Nanocomposites [1,2]

Anti-corrosion coatings [3,4]

Films with barrier properties [5,6]

Membranes for separation [7,8]

Conductive inks [9,10]

Energy storage [11,12]

包装
