Description

technical field [0001] The invention relates to the field of new nano-energy, more specifically, to a polybutylacrylate-polybutylmethacrylate copolymer for flexible nanometer generators and self-driven sensors and a preparation method thereof. Background technique [0002] Nanogenerator is a new type of energy harvesting device proposed in recent years to solve the problems of energy shortage and environmental pollution. It can convert mechanical energy in nature and life into electrical energy through special materials and device design. Since nanogenerators can generate electrical signals based on external stress and deformation, they can also be used as microsensors to monitor the movement or deformation of human bodies or objects, and nanogenerators with high flexibility and transparency have a huge market demand. [0003] Compared with traditional piezoelectric nanogenerators, triboelectric nanogenerators have the advantages of high energy conversion rate, output power...
