Chemi Tech Graphene Dispersant: Solving Agglomeration, Unleashing Material Potential

In the R&D and production of graphene applications, are you often troubled by these issues: graphene sheets readily re-agglomerate, making uniform dispersion in the matrix difficult; manual grinding or ultrasonication is time-consuming, labor-intensive, and yields unstable results; dispersed slurries settle after short storage, affecting subsequent processing and product consistency. These agglomeration problems directly prevent the full realization of graphene's exceptional conductive, thermal, and reinforcing potential, significantly compromising composite material performance.

Addressing these core pain points, Chemi Tech leverages deep expertise in nanomaterial interface treatment to introduce a series of high-performance graphene dispersants. Our solution is not merely adding an auxiliary agent, but involves precise molecular design. The dispersant effectively adsorbs onto the graphene surface, forming a stable steric hindrance or electrostatic repulsion barrier, fundamentally preventing re-agglomeration caused by π-π stacking.

Our specific solution steps are as follows: First, our technical team conducts a detailed assessment of your graphene raw material type, target system, and process. Subsequently, we recommend the matched dispersant model and addition ratio. On the operational level, we suggest pre-dissolving the dispersant in solvent or mixing it with the resin matrix before adding graphene powder. Efficient and stable dispersion can be achieved through moderate mechanical stirring and shear, greatly reducing reliance on high-intensity ultrasonication. The stability of the dispersed slurry is significantly improved, allowing for longer storage without noticeable sedimentation, facilitating subsequent coating, injection molding, or compounding processes.

For instance, a company focused on functional coating development faced challenges with uneven graphene dispersion in resin and fluctuating coating conductivity. After adopting Chemi Tech's customized dispersion protocol, they obtained a uniform and stable graphene dispersion slurry under常规 stirring conditions. The resulting coating not only showed a 70% improvement in the consistency of surface resistivity distribution, but its wear resistance was also enhanced due to the uniform graphene distribution, successfully meeting the client's stringent requirements for high-performance anti-static coatings.

Choosing Chemi Tech Graphene Dispersant means opting for more stable processes, superior product performance, and higher R&D efficiency.
