Preparation and characterization of delafossite CuCrO2 film on flexible substrate

Delafossite CuCrO2 film was successfully prepared on a flexible plastic substrate using a heat transfer process. The metallic acetate of the first layer decomposed to form a carbonized layer for use as a release layer. The thin film was deposited on the first layer by chemical solution deposition and heat treated to form a CuCrO2 film. After that, the delafossite CuCrO2 film was transferred from a Si substrate to a polymethyl methacrylate (PMMA) substrate. The CuCrO2/PMMA film structure, morphology, and optical properties were studied by different characterization techniques. X-ray diffraction analysis and Raman spectrum analysis confirmed that the delafossite CuCrO2 film was transferred onto the PMMA substrate. XPS analysis showed that the metallic acetate was annealed in N2 to form a carbonized layer. The resistivity of the CuCrO2/PMMA was gauged by a four-point probe method, and the visible light transmittance was approximately 58%.
