The emergence of wearable electronic devices has dramatically changed people's daily life. However, the conductivity and wearability of most wearable fabric sensors still need to be improved. Therefore, it is of great importance that wearable, flexible electronic devices of fabrics be prepared with excellent antibacterial, electrochemical, and electrothermal properties. In this paper, a polypyrrole (PPy)/carbon nanotubes (CNTs) composite cotton fabric (CF) was prepared by in situ polymerization. The structure and morphology of the composite cotton fabric were characterized by Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy (Raman), and scanning electron microscope (SEM). The different process conditions were measured with a four-point conductive performance of the composite fabric, using the I−V curve, cycle volt−ampere characteristic curve, and curved sensitivity curve to investigate the electrochemical performance. In addition, its electrothermal performance and antibacterial properties were measured. When the concentration of pyrrole was 0.2 mol/L, the conductivity of PPy/CNT/CF reached 4.5 S/cm. Furthermore, the capacitance of the composite fabric as an electrode in the supercapacitor prototype could reach an order of 34.4 mF cm −2 . It was discovered that the composite fabric displayed a specific capacitive performance, good thermal conductivity, and antibacterial property.

The practical application of fiber membranes prepared by electrostatic spinning requires a uniform thickness. However, the parameters involved in the spinning process are highly complex, particularly when it comes to precise control over membrane thickness. Hence, achieving a consistent and homogeneous thickness for fiber membranes has posed significant challenges thus far. To accurately predict membrane thickness during the spinning process and ensure consistent outcomes, this study employed polyvinylidene fluoride as the raw material and optimized electrostatic spinning preparation using an innovative airflow‐assisted strategy. The as‐proposed preparation strategy effectively enhances the volatilization of solvents within the jet, also promotes jet stretching through assistance from airflow, resulting in a more stable and homogeneous fiber diameter. Additionally, COMSOL simulations were utilized to provide rational explanations for these findings. By collecting multiple process parameters, including positive voltage, liquid supply speed, winding speed, and solution concentration, this study has successfully developed an artificial neural network (ANN) that exhibits reliable predictive capabilities for membrane thickness. Notably, the model demonstrates a remarkable goodness‐of‐fit with an R2 value of 0.9981. Through the integration of ANN with electrostatic spinning technology, significant advancements have been achieved in accurately predicting and controlling the uniformity of electrostatically spun polymer fiber membranes.
