Although polymer-based nanocomposites have great application potential in many fields, compared with the application of ferroelectric nanocomposites in functional microscale structures and devices, especially in the field of photonics microdevices fabricated by laser processing, the development of polymer-based nanocomposites is relatively lagging behind. In this study, the polyvinylidene fluoride ferroelectric composite material was taken as the research object, and the preparation method of polymer nanocomposite material suitable for laser microstructure processing was solved by exploring the material functionalization method. The control of the optical properties of polyvinylidene fluoride ferroelectric composites was achieved through material design, control of the size of nanoparticles in the prepared polymer nanocomposites, and characterization of their structures and properties. Two-dimensional and three-dimensional structures of polymer nanocomposites were prepared by laser microstructure processing technology, and the optical properties of the microstructures were evaluated. When the applied stress field was zero, the macroscopic coercive field was larger, and the hystereswas loop was wider, while the butterfly curve changed rapidly near the coercive field, and the strain was negative. From the test results of the scanning electron microscope, it can be concluded that the lowest average power to find ablation traces was 0.06 mw, and the affected area was very small, and there was no damage to the surrounding nanotubes. Therefore, this paper believes that the damage threshold of carbon nanotubes was slightly less than 0.06 mw. This study contributes to the development of nanocomposite preparation methods for laser micromachining.

As an imperative part of information technology, photoelectric information technology is widely applied in smart phones, mobile computers, portable electronic products, medical care, and industrial technology. In this research, a high-precision infrared photoelectric sensor is designed, which utilizes XDU3093 chip as a built-in photoelectric sensor. The chip has the characteristics of high-power supply rejection ratio and temperature compensation. Then, the focus is on the design of infrared driving module and infrared detection module. Among them, the pulse current of the infrared drive module is more than 100 mA, and the output current is in the form of square wave. To control noise, an isolation circuit between the infrared drive and other modules is set. Infrared detection involves photoelectric sensor. The nwell diode in CMOS process is utilized as photosensitive diode, and at the same time, the surface of the diode is coated to ensure that only infrared light can generate photocurrent through coating. In the experiment, the infrared driver is simulated, and the results show that the driver module can effectively amplify the collected infrared signals, and the detection accuracy reaches 0.2 V. The simulation of infrared detection suggests that there is a linear relationship between photocurrent and background infrared illumination, and the photocurrent decreases with the increase of distance. The designed infrared photoelectric sensor is applied in the soft package counting link of workshop management. The infrared photoelectric acquisition signal is converted into an analog voltage signal, which is processed by the voltage conversion circuit and then transferred to the single chip microcomputer and software module. After the data is uploaded to the upper computer through the serial port, it shows that the number of soft packages can be accurately identified in the workshop soft package counting link based on the designed infrared photoelectric sensor.
