NOVELTY - Preparing flexible film based on graphene micro-cylinder array involves constructing poly-di-methyl-siloxane (PDMS) substrate with micro cylinder array having height of 20 micrometer and aspect ratio of 1-2.5. The PDMS with the microarray is placed in a plasma etch apparatus, treated with plasma oxygen for 10-15 minutes, and PDMS is soaked in PDDA solution (polydienedimethylammonium chloride solution) for 30-60 minutes, then washed with deionized water, and placed in an oven at 40 degrees C for drying. USE - Method for preparing flexible film based on graphene micro-cylinder array (claimed). ADVANTAGE - The method enables to prepare flexible film based on graphene micro-cylinder array in simple and cost-effective manner, and which has high repeatability. DETAILED DESCRIPTION - Preparing flexible film based on graphene micro-cylinder array involves constructing poly-di-methyl-siloxane (PDMS) substrate with micro cylinder array having height of 20 micrometer and aspect ratio of 1-2.5. The PDMS with the microarray is placed in a plasma etch apparatus, treated with plasma oxygen for 10-15 minutes, and PDMS is soaked in PDDA solution (polydienedimethylammonium chloride solution) for 30-60 minutes, then washed with deionized water, and placed in an oven at 40 degrees C for drying. The graphene solution of 0.3 milligram/milliliter is dropped in the dropping the amount of 200-467 microliter/centiometer square, and drying at 40 degrees C to obtain final product.
