CNTs/CF/PU导电复合材料的制备和性能研究
Research on preparation and properties of CNTs/CF/PU conductive composites
摘要
Abstract
A flexible strain sensor based on a conductive polyurethane(PU)substrate with a composite of car-bon nanotubes(CNTs)and carbon fibers(CF)was fabricated using the solution blending method.And this sen-sor is characterized by high sensitivity,a wide strain range,and a simple fabrication process.Specifically,CNTs and CF were mixed and then brush-coated onto a PU substrate to form the CNTs/CF/PU conductive composite material.The Latin square design method was employed in the experiment to optimize the number of trials and parameter range,and utilizes the Multilayer Perceptron(MLP)model for data training and optimization.Under a high strain condition of 150%,contour plots were generated to analyze the optimal sensitivity region.The re-sults indicate that increasing the proportion of carbon nanotubes,increasing the mass of carbon materials,reduc-ing the length of carbon fibers,and extending the ultrasound treatment time all positively influence the sensitivi-ty of the composite material.The specific parameter ranges for the optimal sensitivity region(yellow area)at 150%strain are as follows:CMQ range of 0.08 g～0.1 g,CNT_ratio range of 0.7～0.9,CF_L range of approxi-mately 0～4 mm,and Ultrasound time range of 40～80 min.关键词
