In situ synthesis of ternary BaTiO3/MWNT/PBO electromagnetic microwave absorption composites with excellent mechanical properties and thermostabilities

Abstract

Different from traditional microwave absorbing nanoparticles as fillers in non-mechanical coatings, the BaTiO3/MWNT/PBO ternary composites can be potentially used as a structural microwave absorption device in broader applications, especially in the aerospace industry. BaTiO3 particles with a diameter of 5–15 nm were immobilized onto the surface of MWNTs via a solvothermal synthesis method. BaTiO3/MWNT/PBO ternary composites with varied compositions were then prepared via the in situ polymerization of p-phenylenebenzobisoxazole (PBO) with a uniform dispersion of BaTiO3/MWNT nanocomposites in the polymer-poly p-phenylenebenzobisoxazole (PBO)-matrix (a conjugated polymer with splendid mechanical properties and thermal stability). The BaTiO3/MWNT/PBO composites possessed outstanding microwave absorbing performances in addition to desirable mechanical properties and thermal stability.
