摘 要：In order to meet the demand for infrared stealth materials in the military field,conjugated polymers containing Schiff base moieties were designed and *** dialdehyde monomers were introduced and their effect on the comprehensive properties were systematically *** resulted polymers could be cast in solution to prepare polymer *** coatings exhibited high thermal stability up to 400℃ at 5%weight loss,and excellent mechanical performance with high Young’s modulus and *** infrared emissivity values varied from 0.587 to 0.627 at wavelength of 8-14μm and ranged from 0.595 to 0.609 at wavelength of 2-22μ***,it was found that the ATTPAL structure with carbazole moieties had a lower band gap and better electrical conductivity by photoelectric test and DFT theoretical ***,the infrared emissivity value of ATTPAL coating was the lowest compared with p-phenyl and pyridyl containing analogues,suggesting it was potential material for the future development of infrared stealth *** combined results showed that reducing the band gap and improving the electrical conductivity of the structure were both beneficial to the reduction of infrared *** would positively provide new ideas for the design of infrared stealth materials.
