Breakthrough: coating polymer powder with Aros Graphene®

SHARE

Graphmatech’s research team has succeeded in developing a simple and scalable method for coating polymer powders and granules with a layer of Aros Graphene®, in a leap towards high-quality graphene composites.

This newly developed method is very efficient to obtain high quality dispersion of Aros Graphene® additive inside a polymer matrix without the use of high shear forces in melt mixing. It enormously reduces production costs and minimizes property degradation for both the polymer matrix and the additive while maintaining high quality and homogeneous composite. The invented method can be also applied for coating polymer powder with different materials such as metals, ceramics, fibers, cellulose and etc.

Applications of polymer-Aros Graphene® composites are vast, such as multi-functional filaments for 3D printing, or engineering composites with light weight, high thermal conductivity, high mechanical strength and enhanced tribological properties (low coefficients of friction and wear).
