The Chinese Academy of Sciences successfully synthesized a graphene special dispersant to improve the performance of coatings

Artificially prepared graphene cannot give full play to the excellent characteristics of graphene monolayers because it is easy to reunite. The advanced coating and adhesive technology team of Ningbo Institute of Materials, Chinese Academy of Sciences has successfully synthesized a special graphene dispersant, which has made a breakthrough in the key bottleneck restricting the popularization and application of graphene - dispersion technology, and made these easily redispersible graphene powder The body is used in the field of coatings, which greatly improves the performance of coatings.

According to reports, the team has taken the dispersion technology of nanomaterials as one of the important research directions since November 2013. They have conducted in-depth research and a large number of experiments on the efficient dispersion technology of graphene, and recently achieved some breakthrough progress. Under the leadership of researcher Yu Haibin, the team synthesized a special dispersant for graphene. The dispersant is added into the graphene-containing solution, and a monodisperse water-based and oil-based graphene dispersion can be obtained through stirring treatment, and a graphene powder that is easy to redisperse is creatively prepared.

Currently, the team has applied these easily redispersible graphene powders to the field of coatings, and the performance of the coatings has shown great improvement. This dispersion technology will help graphene achieve breakthroughs in the application of anti-corrosion coatings, anti-static coatings, conductive inks, transparent conductive films, supercapacitors, battery materials, and heat dissipation materials.

It is reported that this technology and related products have applied for 14 national invention patents. The research results have a significant role in promoting the industrial application of graphene.
