Abstract：The integrated materials of anti/de-icing-stealth have important research value and application potential in aerospace,especially in the field of UAV.In this study,graphite/silicon based gel composites were prepared by siloxane coupling reaction.The results show that when the graphite content is 40％,the hydrophobic angle of the silicon based gel is 109.3 °±2.3 °,the temperature in the center of the sample is 69.6 ℃(heated at 100 ℃ for 60 s),the maximum tensile strength is 0.512 1 MPa and the effective absorption bandwidth is 6.83 GHz@1.61 mm(9.70～16.53 GHz).The intrinsic coupling mechanism of hydrophobic,thermal conductive and micro-wave absorbing properties of silicon based gel was clarified by characterizing the microscopic factors such as con-ductivity and defects of gel.This study provides a simple material design strategy for achieving both stealth and anti icing functions of drones simultaneously.
