Main results
Technological results: Successfully manufacture equipment for producing multilayer graphen materials with adjustable capacity up to 01kg/day.
Theoretical results: Develop a process with technological parameters for producing multilayer graphen at a capacity of 01kg/day.
Applied results: Initial results achieved in introducing the nano graphen leaf product of the task to the following companies:
+ No 75 Rubber Company Limited, General Department of Defense Industry
+ QC Technical Rubber Company Limited.
Novelty and actuality and scientific meaningfulness of the results

The research results have provided a method and a complete system for manufacturing multilayer graphen sheets from graphite compounds through rapid thermal shock heating to separate the graphen layers. This is a relatively new technology with key advantages including simplicity and feasibility of the method and equipment, energy efficiency, easy scalability to large-scale production, enabling the manufacture of large quantities of high-quality materials at a lower cost.
The multilayer graphen materials produced using this technology have been evaluated for their physical properties, which have shown to be comparable to those of similar materials manufactured using existing methods (such as microwave heating). Additionally, the obtained materials have undergone preliminary testing for applications in composite materials (such as rubber and polymer composites).
